The TENS unit is very similar to what the Chiropractor uses. Stim machines are used not only in Chiro offices but in probably every trainers room in college and pro sports. I have used Icy Hot unit but you do much better if go to the sites that sell them. Every Chiropractor I have gone to uses a Stim machine before doing an adjustment.
Hey ZPJ, just wanted to let you know since I started working out again the pain is gone... the 1st weeks were terrible especially when jogging uphill but the pain flat out dissapeared 2 weeks afterwards...! Thanks for your concerns a few months back.
