Pain after shingles PHN mostly by natural methods.?

Been on Gabapentin (neurontin) and Tylenol. Started Jan 31, of course all blistering, and scabing is done. But the sharp and creepy crawly pain is still there. Am I to impatience or is there more to this? If I do any physical activity, the pain seems worse. Sleeping is so hard. Not 8 hours by no means. Gabapentin seems to make me depressed. I am only on 3 a day, tried 4 and I really felt so down. I have gained weight, and food is always on my mind. I am trying to do more every day. But it is always there. Thank You.
