Starting indomethacin (25mg 3x) for post concussion headache, was on fioricet (acetaminophen butalbital and caffeine). Already on topamax (25mg 2x) for migraine. Interactions? I am 5'4" 107 lbs

Seek a neuromuscular. Taking medications is like giving a bandaid instead of stitches seek a neurologist to find out why you have migraines it is quite possible it maybe due to your bite look for a neuromuscular dentist in your area.
Indocin (indomethacin) Need state question clearly. Confusing when say migraine interaction. Concussion- post- are migraines but other varieties. Stay away controlled substances. Topamax (topiramate) excellent prophylaxis- dose usually titrated.Special hemicranial headache where indomethasone is drug choice. One sided, severe, stop go several times day. Common post trauma is cluster headaches. Diagnosis of headache is 95% history. K.
