postherpetic neuralgia
"Had a Thalamic Stroke, which left me with disturbed sensations on my right side.  10 years later, developed shingles on my right leg, which I thought were bug bites.  Within 3 days, I was in agony, after 8 weeks I was loosing functionality in the right leg.  Saw Orthopedist, Pain Specialist, and received the impression, that they thought I was a nut, or trying to get pain meds.

Finally went to a neurologist, who diagnosed TPS and Shingles nerve pain interacting. Within 24 hours of starting Lyrica the pain lessened, upping the dose a few weeks later and the pain was zilch.  I have started to regain function in the right leg, it's very slow but I can see it.  I have never felt such terrible pain, Lyrica was a true lifesaver."
