Hi Catra,

I too have the EMPI unit and have used it for about six years. I did not get much instruction with mine, it was just trial and error. But I can tell you I use many different levels for different areas and I use it at least twice a day. You kind of have to try different levels at a low dose. Usually when I use mine on my right foot that has severe causalgia, I have to use a higher level to get pain relief. My hip I use a lower intensity due to the sensitivity. You will just have to experiment for awhile to see where your comfort zone is at. However, I do agree with Daililyfan, the supplies are expensive especially when used on a daily basis so do be sure that expense is covered by insurance.

This has been a great alternative for me, I hope you have the same result. Best of luck.
