my daughter is 14. She is a dancer. She has been complaining of pain in her ankle. She was seen recently by our podiatrist. He prescribed a compound cream to be applied 3 times a day, also soaking of the foot and using a TENS unit. When I turned on the TENS unit, she can't feel the electrical impulses. I got it up to level 10 and she could barely feel it. I have called her doctor twice and have not had a return phone call. I am concerned.
