runs until about end of Oct. This year it started in May when we visited Panama and is still going on. I've tried every otc and prescribed cream out there to no avail. My GP prescribed Gabapentin for lower spine injury and upped it for this recently but that hasn't helped. I tried spinal decompression at the chiropractor with no relief. I have it in both arms now concurrently and in my right arm it runs from shoulder to wrist. Like another sufferer here, only ice or knocking yourself out seems to help. I take ice packs everywhere. I have severe disabling tinnitus as well and it's worse when you're tired. Between the two things I feel like I'm going to go crazy. I'm a retired RN. This started right after I went on long term disability in 2012 after a bad car accident and I'm just glad I don't have to work now because it's a nightmare. I'll check into the treatments you mentioned because I'm desperate. Thanks again and all the best to you and fellow sufferers everywhere.
