I just wanted to let you know you can get lidocaine patches to put on your back, knees, shoulders, wrists and neck. It numbs the nerves under your skin. If it's really bad you can put tiger balm under the patch. Also there is a higher patch that has Advil in it called Diclofenac. You have to ask your doctor for a prescription. Ask for 3 a day supply which is 3 boxes per 30 days.
