Hi Karin,
I know that you have a TENS unit and I am thinking that you might want to dig that out again and give it a try. Yesterday I received an Interferential Unit in preparation for my MIS TLIF so I decided to give it a try so that I would know what it would feel like after surgery. In addition to my L5-S1 DDD I also tore two shoulder muscles. My shoulder pain rivals my back pain so I thought I would try the unit on my shoulder. WOW, I can't believe that it really reduced the pain. My understanding is that the unit is stronger than a TENS unit so if your pain persists maybe you can inquire about this product. The rep said that there are a lot of competitors out there so you should be able to find a source if you are interested. I plan on using it on my shoulder until the surgery since I can't get to an orthopedic surgeon until after my fusion. It would be so great if my shoulder healed without having to go to yet another surgeon!!!!
Hang in there Karin and take it easy!
