Hi... I believe different sufferers of migraines can show a variety of symptoms.
The main one tho' tends to be that it's mainly down one side of your head, whether that's at the top, or temple, or ears and behind the ear, back of the jaw and into the neck.
Also behind your head.
It can also be a continual pain, or an intermittent "lightning strike" pain.
Some also experience nausea, or actual physical sickness.
Some get aura with or without pain.
There are a LOT of preventative meds, some of which may work for you, or none may ever work.
The test time to take each kind of preventative med is roughly two to three months, so it can take ages to find a preventative that might work for you.
The usual painkillers are meds that are "triptans" ie sumatriptan, rizatriptan and I think about four others.
I've had migraines for over forty years, and of all the preventative drugs, treatments, injections (Botox etc) there has only been ONE type to help me....
...................................it's an anti cgrp injection, I had it prescribed to me about twenty two months ago, and whilst they haven't disappeared altogether, my intake of painkillers has reduced massively down to under twenty doses so far this year alone.
I would get yourself referred to a neurologist OP, and while your waiting for an appointment, keep a pain diary of the days you get an attack, note whether it's a one out of ten pain or a ten out of ten pain, or anything in between.
Also note if you took a painkiller and how many that day.
The neurologist tends to ask for this info.
Oh yes, and whether you notice if you get your attacks around a period or not, as some migraines are hormonal.
I likely haven't remembered to mention everything, but above is a good start.
You may also want to note if you think certain triggers like noise, light, smells, or foods , too much sleep not enough sleep, start you off.
This is complex, as some people have a combination of triggers.
Some people get very emotional with an attack, and I've found that my capacity for memory has greatly reduced.
It certainly doesn't help when your told by friends and family " oh yes, I get bad headaches".....
I feel fo you OP, and I hope you find help very soon.
