There are several products with 4% Lidocaine on pharmacy shelves. I find the all work about the same. I also have a massaging heating pad that I use in conjunction with this. Between the two I can get total temporary relief. For more permanent relief, you need to build your small muscles. Get a referral to a PT.

I'm sorry, I don't have any suggestions other than to check with your Dr for possible advice. Maybe he can suggest stretching exercises to do?
