I have similar problems, osteoarthritis, bad discs especially lower spine. I try to walk minimum of one mile a day but now I sometimes get sciatic/hip pain on my left side. Nothing helps except I do have a jacuzzi tub ( not a spa) and the warm water helps ( can’t get the gets in the right spot 😳). My car has heated & cooled seats with adjustable lumbar support. But I cannot take anything like Tylenol. My doctor did prescribe a dose pac of steroids once; im saving it for our upcoming driving vacation. Not looking forward to walking all day either
