I am really suffering every day from phn on one butt cheek only, but the pain stops at my anal opening, which is where I've suffered the most excruciating pain, in such a sensitive area! I really feel like I must be the only person to have contracted shingles in such a weird place and for so long too, as it has been with me every day since April 19, 2014. My regular doctor tried me on every shingles medicine on the market today, in ever increasing doses to no avail. I've tried acupuncture, homeopathics, essential oils, supplements, etc. but the pain is not alleviated. My level of pain during the course of a day could be anywhere from a 2 to an 8. I never know what to expect. I do know that I hurt the most at night when I try to go to sleep. I literally change positions over and over. Front, side, back, side. It's like being an alligator who rolls over and over with it's prey in the water. I just cannot get comfortable enough to go to sleep. I beg anyone out there who even remotely shares my experience, to answer with any suggestions.
