Last Update 3/29/16: general staus update and some details on how the pump's catheter was placed and drug amounts.
This is the follow up procedure to my nerostimulator implant in Sep 2014, I documented that over a few months on the topic below.
http://www.pudendalhope.info/forum/view ... =33&t=6188
I will try to document this in a similar fashion as the stimulator.
Before I get to the trial, my best advice to anyone with PN is to memorize the pudendal anatomy as best as you can, this site has lots of reference material on the home page. I have found the doctors will take what you are saying much better if you can speak their language or earnestly try to. If you get it wrong they will tell you, they will appreciate your efforts, and it will help them understand that you are an active participant in the process and not just "following along" like most patients.
Also, study your previous procedures get the records and notes for yourselves, I have 400 pages of medical notes for just my PN stuff. I am the ONLY one who knows it all, if they misstate anything let them know politely ,remind them of details that are relevant especially any bad reactions or procedures that have failed din the past.
I they are trying to repeat a procedure that did not work, like nerve blocks, ask how this procedure is different. I found out that my old pain clinic was jabbing the nerve constantly and blasting the nerve with the injection. When Dr. Ross did the injection it was, much less painful and had the same effect.
Understand what is going on, PN is not common so make sure YOU know what is going on.
OK, now to the pain pump.
A Brief History
In 2012, my second surgery they found the PN entrapped in one place, and adhered to the sacrospinous ligament. Basically the damage was done, and after 2 years of intense therapy and 17 months of disability, I have little to no recovery.
I have been in major chronic pain and taking opiates around the clock since 2010, between the stimulator, PT, and opiates nothing was managing my pain and giving me a decent quality of life, I spend 20 hours a day in bed.
I am totally unable to sit since early 2010. A hard surface feels like my testicles are being squished when they are not. A soft surface will make the pain slowly creep up until I have so strong a sensation that I MUST MOVE. Either way, that would flare me up for the rest of the day. Driving is easier as the car's seats are bolted to the floor so I can use my left leg to lift up my left side to prevent pressure to that area.
The two primary Doctors I see are:
Dr. Ross, is the director at Brigham and Womens pain clinic in Boston, MA
Dr. Vaninetti, Fellow of Dr. Ross
Dr. Ross has a small army of fellows, I have met about 7. This is good in my opinion, he can delegate tasks and get more done. They are all very good and focused on PN, they have all listened to me and understand the issues. the appointments are close together usually 2-3 weeks. I always talk to the fellows first and meet briefly with Dr. Ross, he IS quick but has taken the time for questions. Make sure you have question written down.
The fellows always seem to have read my files, and have always acted like the care, they have never discounted my opinion like with other pain clinics.
The event that brought about the pain pump was that my opiate tolerance was getting worse. I could not tolerate the Fentanyl patches and I was frustrated with walking a tightrope of pain and being able to function. Is was so narrow I would be incapacitated in pain if I missed a dose by two hours.
Dr. Ross said there were two options open:
1. subaxone a different type of pain killer like methadone
2. pain pump
After I had investigated both, I decided to go with the pain pump. Dr. Ross performed a single pain injection to confirm that the procedure worked and "OKed" the trial. He also started the subaxaone process as a method of weaning off of pain killers.
At the next appointment he presented two options for the pain pump.
The first is the standard "pain pump" that is put in the intrathecal area of the spine where the spinal fluid is, it would be located up in the traditional location but pointed down towards the sacral vertebra instead of the lumbar.
The second option was to have the pump deliver a local anesthetic at the S2 area, this had the advantage of not having to worry about building a tolerance to opiate medication and that it would lonely affect the pudendal nerve and possibly some transient numbness on the legs.
This is the same pump used in the spine is put in the pudendal canal using different medication, so that the pudendal nerve has a local numbing medication constantly placed around it.
After the details were worked out I was scheduled for the trial, due to insurance issues and his avalibility I was scheduled for the trial the next day.
3/16/15
My trial is tomorrow 3/17/15 and it requires a 3 day hospital impatient stay, so I may not get to updates for a couple of days. The surgery is scheduled for 4:00 PM so my whole day is going to be waiting.
As always any prayers are welcome, and I will keep you posted.
The place holders below are to allow the description of the process to be in one easy to read location, I will use them as I document things.
3/17/15 Surgery day
I got into my hospital room and it is bueatful, I am on the cardiac ward, due to the epidural, and I am hooked up to a IV, ECG, and an O2.
The check my BP and O2 every 2 hours.
So far the pain is minimal, I do press the button every hour or so but the pain is way down.
The trial surgery was easy, I think, I don't remember a thing

The epidural is placed inside the "butt crack" way below S6 this is going into the lower bowel of the pudendal canal. It is not uncomfortable, the taping of the epidural up the back is the most annoying part.
Tired and my back is sore but other than that I am OK. My wife is here with me, my daughter is with my brother at home, this is sad but I get out of the hose so little that we almost consider this a date.
3/18/2015 Hospital day 2
I was worried about the numbness, but it is really small I can just barely tell that there is a difference from the left and right side.
6AM
I decided to NOT take my 15mg of Oxycodone, my pain is minimal so Lets see how long I can go without it.
I did take my MScontin 30mg, as a way to prevent any withdrawal symptoms.
The next morning I tried walking around the nurse said I could so I carefully started to go out. Within a minute or two Dr, Ross's fellow showed up and I kinda and got in trouble,

10AM
I still decided not to take Oxycodone that is 2 doses missed I should be in a fetal position unable to move and in agony. But I feel fine, WOW this is great!
Later that day I tried sitting...yes sitting I was ok for 2 min before the first twinge and pain appeared, I got up and hit the button, and that seemed to take care of it within 90 seconds.
2PM
Declined oxy for the third time !

I did take Mscontin on schedule.
I broke out my laptop and was able to post a little bit.
Dr. Ross answered and said that I could ambulate outside my room. Freedom!!, I am now one of those guys walking around with the IV rack, Don't worry I actually put on some old sweat shorts. I immediately get to the mini kitchen on the floor and find a fresh pot of COFFEE, as I walk back past the nurses office I do my best impression of Gollum from lord of the rings "Precious, my precious COFFEE.." That got a good laugh..

I continued to have a small amount of PN pain that the bolus keeps at bay, I was pressing the button every hours or so.
At about 5PM during the shift change for the nurses I realized that I had pressed the button 26 times in the first day, any time I felt the smallest twinge of pain. That evening they upped the dosage to 2ml an hour.
6PM
Declined oxy for the fourth time !

The increased dose reduced the need to push the button as much and allowed me to rest a little more.
8PM
I also got to Skype with my daughter before bed. If you have kids, I recommend that you setup a way to Skype and talk to them, it helps a lot with their anxiety over the surgery to SEE that you are OK. Just make sure that you set up the Skype before going to the hospital, that way there are less problems getting it up and running.
10PM
Declined oxy for the fifth time !

Due to the increase they had to constantly check for any numbness, BP and O2. I did not sleep much.
2AM
Declined oxy for the sixth time !

Finally got some sleep from 2-6AM
3/19/2015 Hospital day 2
7AM
I did not sleep well... Got some breakfast and a cup of coffee, listened to some music. I am still at a pain level of 2, I feel great. I could seriously run a mile if it was not for the epidural. The pain has been so bad for so long that I had forgotten what it was to not feel pain.
9AM
The nurses wanted to ask me some question about the stimulator and I was happy to answer them, we found out that charging my device did not effect the ECG.
Dr. Vaninetti comes by while I am walking and taking with the nurses and is beaming with a smile, he looks at me and says things are going great and that there is more than enough proof that this should work, he explains that the pump is more effective than the trial and that the relief I am getting with the epidural is great.
I am going home a day early. Dr. Vaninetti says to call the office and schedule a preop and to ask for a surgical date. He then starts my discharge papers.
He also says that before I leave to start back up on all of the pain meds, in about 10 hours the pain would be back in full force.
2PM
My family shows up and I get discharged, I take a min to go to medical records and get a copy of surgical notes. They give them to me while I wait.
5PM
I am home, we just missed the afternoon traffic. It nice to be home. I stil feel great and my daughter is estactic that she gets her "old papa" back for a few hours.

Lessons learned:
1. If you are a guy shave your chest and back. The epidural is snaked up your entire back up to your shoulder. This is in case you pull it there is plenty to rip until it actually get to the epidural. Taking off the entire bandage is a one shot waxing of you back.
2. You upper chest too, the 3M red dot leads stick with adhesive that takes everything with it and leaves a nasty sticky square that takes a couple days to come off. I found mineral oil work well to unstick it.
3. Underwear, You can wear underwear or lose shorts. Pack 5 or 6 clean pairs, the surgical site does ooze and bleed a little so you will need to change the shorts once or twice a day. If you don't have them buy a pair of boxers that are not too flashy. This helped me feel more comfortable and don't feel exposed while walking. I don't know about sports bras but I think you could get away with those too.
4. Entertainment, bring something to keep you busy. I felt like a million bucks and I could not do anything. I am glad I had my laptop with games on it.
Now I am waiting for the confirmation of a pre-op and a surgical trial.
