Had 2 in my neck. Had surgery in May. Still some pain on rainy or cool days. In such pain I had to have relief. Was actually looking forward to the surgery for relief until in the operating room and they told me they were going to put a catheter in. HELL NAW!!!!!!!!!! You can't put a garden hose in a McDonalds straw without ripping something!! I'm still kinda partial to the little fellow. They agreed to go in and out while I was knocked out.
