Hi Beth,
Welcome to Healing Well's chronic pain forum. I am glad you found us but sorry to hear you are having so many problems. We do have some members on the forum that are having success with the SCS. The problem with your legs should be taken up with your dr and the rep from the company that made your device. If you have a good rep from the company he can fine tune your SCS with no problem. it does take some tweaking many times with the units. None of the members here are drs, therefore, we really cannot answer your question.
I do urge you to do a quick search here on the forum about the SCS and you will be able to pull up a lot of info about them. They have been discussed here many times. It would be much quicker to search the info rather than waiting on one of the members seeing your post.
I wanted to pop on and tell you welcome aboard and I hope that you will post and let us know how you are doing. Take care.
