I had a CSF leak repair and a mastoidectomy 15 months ago. Everything went fine. Currently I have stabbing electrical-like pain in my scalp, ear, temple...it hurts like hell. I've been having it for 4 days now, I had it one month ago, three weeks before that, three weeks before that and three weeks before that. It seems cylical, and its not always on the same side as I had the surgery, sometimes its in the opposite. I get stabbing pain in my ear or temple, it lasts a few seconds and it comes on a few times every minute, for a couple of days. What do you suspect?
