I'm a 69 yo Vietnam vet. With severe low back pain. Have tried just about everything including opioid pain pills 7.5 hydrocodone 5 pills a day. Still no relief. Tried the tens unit it helped a little not much. The va is going to give me an alpha stim m stimulator. I try it at the va. It seems to really be helping with the pain. It also has ear clips. I use the ear clips to help me sleep. It really works. Getting much needed sleep when I use the unit. I'm looking for other suggestions. I also have nureopthia in both legs. Can't walk very far. Wife pushes me in a wheelchair. I'm going to try to exercise and swim next. Hoping the alpha stim m will lower my pain so I can walk. When I try to walk the lower back pain is to severe. And my back locks up.
