I've seen them in Walmart for about $5.00. I use a rounded tablespoon of epsom salts to each side, and enough warm water (not hot) to cover my feet. In the summer you can use cool water. I've had a physical therapist treat a swollen running injury with TENS and ice water.

Sessions should be about 1/2 hour each. I wouldn't do more than 2 a day. The power level should be very noticable but not at all painful. The goal is to stimulate and soothe the nerves and muscles for pain relief and to promote healing, not irritate them.

After each session, I pat dry the skin and gently massage with skin creme. Anything soothing and protective will work.[/QUOTE]

Can I use any tens unit? I have one already or do I have to by that $500 one :0
