Hey Smoke
read the other thread [stimulator friend or foe] what galen said make sense and others here like fmike and others told me the same,,,i think im in sip pain and not smp anymore,it makes a difference on how a stimulator or TENS will react on you, IF your smp,,then you should get relief,,but if its progressed to sip,,then it will agravate your symptoms,,,,,youll know about acouple of hours after you take the unit off,,,i had terrible flares,,,,some are telling me that a stimulator will make it spread worse for me,,,,,either way,,,take care brother,,your in my prayers as well, also my condition mirroed from one leg to the other too;;;But dont worry stay calm, and stay active,,,,and if you have access to a pool to swim or aqua jog,,,do it,,its been making my condition recede, , God is good and does answer prayers,,,,,,,,,,,,,your friend in Christ Jesus,,,,,bobber
