I'm sorry to hear about the progression of your disease. It sounds a lot like mine as far as the speed with which it progressed. The "good" news for me is that it is still limited to my left leg only, although it has spread beyond the original distribution of the damaged nerve.

I agree with daniella, early treatment is best. There are some other good drugs/combos out there that can help if the Lyrica isn't cutting it any more. Hang in there.
