doctor, early 1990;s, neurologist said I have a sensory/periphal neuropathy. I have tried CABAPENTON, and one other pill , did not work. I ve asked my V.A. doctor to order lanocaine , but he said the pharmacist said, long term use might cause HEART problems. I have NEVER had heart problems. The neurophy is located feet, ankels, hands, wrist, face, neck and TO THE OPENING to my ear canal. this location drives me crazy especially when I try to sleep or go to sleep. IT IS ONLY at thew opeing of the ear canal. NOT inside the canal. ONLY where I could put my finger at the opening. He has recommended HYDROCORTIZONE cream top 2.5% . I NEED SOMETHING THAT WILL numb the ear canal OPENING like nandocaine. What is your openion?
