My Migraine Nightmare: How Dental Work Triggered My Headaches

My Migraine Nightmare- I am 100% sure without a doubt that the onset of my migraines happened in result of dental work. I had a root canal on April 27th... I've had a headache EVERY SINCE and its now OCTOBER. This.... so called headache was in full force by April 29th.... but at that point I was unsure why! by June... i made 2 trips to the ER... diagnosed with migraines in July... we started backtracking cause my health was slipping fast and I literally was going crazy... so I thought. Turns out I had an infection in my brain i did 2 rounds of antibiotics and steroids. I also spent 3 weeks in a ice hat 24/7. (Jesus and I were in direct contact). it was not pretty. Once we pinpointed the root canal I returned to the original office and they suspected and referred me to an endo. I made 2 emergency trips to the endodontist at the office in Muskogee and it was confirmed the root canal was incomplete but they couldn't do anything about it because of the infection and that doctor was leaving and had no openings. i found another endo but he is on the fence and referred me to the neurologist, right now the neurologist has me on 4 different medication just for the "headaches". That is where I am now.... and the headache is better but it's still an everyday thing! we're still waiting on what to do about the root canal. some days the headache is gone but thats when my face hurts... and it feels like i could split into. ..... when that happens i prefer migraines!! My Triggers: underlining squealing, the hum the car makes going down the road, the consonant sinusitis sound thats not there!! CHILDREN SCREAMS, Loud Thumping Base sounds in passing cars, squeaking AC fan in ROSS....... i also have a personality thing to deal with and this cramp a d PAIN is really ticking me off. Do you know the onset of your migraines?
