surface leg pain

Surface leg pain,  groin, hips to knees and if it worsens, all the way to my ankles. CLOTHING or covers touching my legs at night creates such discomfort that sleep for more than an hour or so is impossible. I get relief just by lifting clothing from skin contact. I am more comfortable standing than sitting. OTC pain remedies do not help. Have some L4/5 and sacral issues but when those are ok the surface leg pain persists. I have had experiences where while relining the pain has over an hour or so simply melted away and without any reason. Tried all the Carnitines, Omega 3's, iron sups. I do take B-12, B-6 and D-3 along with 80 oz's of water per day mostly to aleviate cramps. That part works.
