There are hospitals with electrotherapy instrument recommendations?

Recommend that you try to times benefit Kang medium frequency electrotherapy instrument, this thing is really good, some time ago, lumbar disc protrusion hospitalized for a few days, the hospital used to times benefit Kang, I think the effect is oh very good on the purchase of a home use. Now go to work one day, leg a little pain, come back from work to treat a little, can relieve the pain greatly, very recommended.
