Desi,
I'm sorry that it is causing more pain. Stop using it, and let your doc know what is going on. If it is hurting like it is, he should know about it. My pt gal would only do what doc told her to do. One Sat. she call my doc at home as he found a very small soft spot. I told her not to call him at home, and she said she was required to notify the docs of anything she found. She said that they are not able to treat anything other than what doc ordered. She would have to get permission for any type of therapy such as whirlpool, etc. You don't deserve anymore pain. maybe a good day to do nothing and watch tv, read, etc..
your friend.
