I have the same problem. I am wondering if you may have Neuropathy. This is what my doctor told me was causing it. I took Neurontin for a couple of years, but it did not do much good. I have had this problem for years too. I don't think that you are weird at all. I don't know how many others have this problem, but I think that there are others too. I just try not to bump my legs and stuff and I always wear slacks as the cold on my legs will get them to hurting too.
Lupus for many years. Like most of my life. Sjogrens that started at 35 and Scoliosis, Spinal Stenosis, Degenerative Disc Disease, Osteo-Arthritis of the spine, Ankylosing Spondilitis, Periferal Neuropathy, mild CP and now just recently diagnosed with PA. I had a disc replaced in December of 2007.
Plaquenil, Sulindac, Imuran, Celiac diet, Tramadol and B12 shot once a month.
