lyrica advice

[esthome]

I am on lyrica 200mg so far but it has done nothing for my pain. My Gp has advised me to go up to 300mg in total but I'm beginning to wonder if there is any point. It has caused me to have low blood pressure so I feel dizzy upon standing but I can deal with that as long as I see the benefits of taking it. I've been on it now for approximately 6 weeks increasing slowly. I really want this tablet to work for me so am I being impatient or do I need to continue and maybe increase past 300mg. I'm also confused as to why I'm getting new nerve pains, jabbing in perineum area/ inner thigh when I'm on this and amitriptyline. I thought the point of medication was to block pain.

I also start physio next week. Physio wants to try desensitization. I'm scared it will flare things up but I can't carry on the way I am

Any advice is much appreciated.
