i was diagnosed with an AVM last august after having a seizure. i had 2 embolizations and a craniotomy to remove it from my right tempral lobe. its been 10 months since my surgery and it seems like ive had a headache everyday since. my NS doesnt seem to worried about it, he did give me another ct scan to see if something might be cuasing these. they are not horrible headaches or migranes, just very irritating. my nuerologist seems to think it may be rebound headaches from taking too much advil&tylenol, havent taken any in 3 months now, still persistant headaches. is this normal? will it get better if so? also occasionally my head hurts at the location of plates and screws is this normal this far out from surgery?
