I had my last shunt revision 11 years ago and have had no problems until March of last year when I have experienced chronic throbbing pain on and off on the tube and around it from the incision in my neck down to my chest. I went to see my neurosurgeon and he said everything is fine so he sent me home with tylenol with codeine 3 to help for the pain but nothing seems to make it go away I went to see a neurologist for the pain and he knew nothing about shunts but had prescribed me topomax which I took one every night 25 milligrams which lasted for a month but did not help the pain in my neck but helped with the headaches so then he was going to prescribe me nerve damage pills and i refused so i am wondering if anyone else suffers the same pain and any advice on getting rid of it. It comes and goes at random times.
