The initial outbreak of shingles I had was accompanied by viral meningitis which was diagnosed vy a spinal draw and brain scan. It's now been 17 months that i have been challenged with PHN in mid-section area for which I have tried Cymbalta, Lyrica, Vicodin, Tramadol, Gabapentin, acupuncture, Indigo bio-feedback, neural therapy (injections of a procaine-like substance into scars to energetically create anew nerve path), three different procedures to try & identify the nerve in the spine causing the issue. Nothing seems to help, but I must say that if I compare the pain to that of a year ago, it has diminished somewhat - I am grateful for any small improvements! The chronic pain is beginning to wear me down and I feel horribly depressed. Thus, am considering the marijuana. Would appreciate any input. Thanks
