I am a new member. Have disk problems in the L4, L5, and S1. Been told I have Osteoarthritis and degenerative arthritis but for the past 6 months I think I have a sciatic nerve problem, possibly pinched because my lower back at the tailbone is horrid as well as the burning pain in both buttocks and down both legs. I solved the day pain by stretching twice daily and 40 to 60 minute walk daily and also purchasing a TENS unit. This unit has dropped my pain to zero during the day but I wear it for at least 10 hours. My problem is at night when I sleep. I wake up an hour after falling asleep with my back severely tightened up and severe burning pain across the tailbone, both buttocks and down both legs. I cannot sleep at night because of this, cannot get comfortable. Have tried everything, firm mattress, sleep on side with pillow between knees, nothing helps, the tightness and severe pain starts in while sleeping and continues the entire night. I only get about 4 to 5 hours of very interrupted sleep. I've been going to a chiropractor since 1999 but he said I either have a muscle problem or nerve problem. Treatments were not helping so stopped going as it was costing too much money for no help. Does anyone else have this same problem or can anyone offer advice?
