I had shingles 51/2yres. ago. Since then I suffer from post herpetic neuralgia. I have had pain management surgery (epidural), take Lyrical which has aided in alleviating some of the pain, and now I m seeing an acupuncturist. The internal ache and pain has been reduced but the Surface pain exists to the point that wearing elastic waist, Any slacks with a waistband is very painful so I have had to fold the and down. Is there any relief where I would no longer have to take Lyrica acupuncture? I understand that this condition can last for years, which is the case one, or forever?
