My TENS unit is one of the only things that makes a significant impact on my pain levels. I wear it every day and run the wires under my pants legs. It helps for my ankle because the pain is in a relatively small area and I can surround that area with the electrodes and it helps with the pain. When it's the more generalized burning pain over a large area...then it doesn't help much. On the other hand...when I get my bad bone crushing flares (which tend to be in a specific spot) then it can help with that pain even if it's in my upper body where the pain is more generalized as opposed to in a specific spot. Does that make sense?

When the pain is particularly bad then I will use the TENS in combination with a heating pad for the best relief.
