My husband was on 3600 Gabapentin a day at one point, so you can certainly go up, but gradually. Lyrica did nothing for him at all - but everyone is different.

Having said that he doesn't suffer so much vibration/tingling - pain is the dominating feature. Excruciating, can't think, move or function pain. He is now on a Fentynol patch which has helped, but the pain is still always there in the background.

I think you need to get good pain management help, - there is no need for anyone to suffer. Good luck.
