Suga, this can be exacerbating the problem. OTC painkillers can cause what is called REBOUND headaches. The more you take them, the worse it gets. I had it happen to me when I lost insurance coverage and could not afford my migraine medicine (it costs almost $300 a month without insurance). I bought some kind of cheap OTC crap from Bayer dubbed "migraine relief" and it made my migraines better, originally, by "dulling" them. They lasted much longer but were "dull", as in "3 on a scale of 0-10". But then I started getting more and more of them.

Finally I got the right prescription medicine by having somebody buy the migraine medicine in Russia at 1/4 or 1/5 the cost in the US, and now I have enough for the next 3-4 months. Since I stopped using the OTC painkiller, the frequency of the migraines has gone back to what is "baseline" for me (no more than once a week). And, it actually aborts the migraine attack rather than making it into a "dull" headache that then lasts for 24-36 hours.

I am not sure this is relevant for you - I am just picking up on your description of the headaches as "dull" because mine were EXACTLY that when I used OTC painkillers.
