your mention of painkillers makes me wonder whether you're having medication headaches:

"you may have a bad spell of tension headaches or migraines, perhaps during a time of stress. you take painkillers more often than usual. you continue doing this for a while. therefore, your body becomes used to the painkillers. a 'rebound' or 'withdrawal' headache then develops if you do not take a painkiller within a day or so of the last dose. you think this is just another tension headache or migraine, and so you take a further dose of painkiller. when the effect of each dose of painkiller wears off, a further withdrawal headache develops, and so on.

a vicious circle develops. in time, you may have headaches on most days, or on every day, and you end up taking painkillers every day, or on most days. some people start to take painkillers 'routinely' every day to try to prevent headaches. this only makes things worse.

the headache of medication headache is often described as 'oppressive' and tends to be worse first thing in the morning, or after exercise."

you might find it interesting to do a search on the phrase medication headache - i had a short period of this and it was very intrusive - regardless, i hope you find something that alieviates the pain soon
