Hi I have been suffering from severe low back and hip pain for almost a year. I don't know if I have a lipoma or not, but I recently read an article describing the "back mouse", which is a fat herniation under the muscle. I believe this may be what I have going on. I have seen 3 orthopedic surgeons, 2 chiropractors, a rheumatologist, a neurologist, my primary physician of course, a masseuse, and an accupuncturist, oh and 2 physical therapists. No one has given me a diagnosis and I am at the end of my rope. Everything that has been suggested as a cure as made the pain worse. The massage gives releif for a few hours, but that is it. The muscles that run from my low back on either side of my spine down to my but feel like solid steel rods. I am most comfortable standing or lying flat. I also have severe pain in both hips that occasionally runs into the psoyas muscle. I have not been able to engage in any physical activity in almost a year and that includes no sex, because the pain in my hips and back gets worse. I am 29 and in relatively good health asides of these symptoms. I do also have plantar fasciatis in both feet and a sleep disorder called sleep paralysis. Everything may be linked but I don't know. So far the article about the fat herniation under the muscle was the best description.
