Hey - the hotness feeling can be a sign of autonomic activation, and the all-day dull ache combined with that could mean hemicrania continua. Look it up and see if it fits.
If you have a neurology, or your primary doc would prescribe it, then taking indomethicin should be 100% effective at killing this type of headache. In fact, response to indomethicin is one of the diagnostic criteria in the IDH.
The heavy-head feeling could be an aura-type or prodrome symptom, like lightheadedness and dizzyness, which could be connected to migraine-type headaches or seizures.
