Thanks, that's actually a good guess but I forgot to mention that Fibromyalgia was an option I tried to get diagnosed for but it got eliminated, I think the main thing that convinced the doctor it isn't not Fibromyalgia was pain points testing: he applied pressure to specific areas but the pain is hardly affected by pressure (or heat, which you asked about).
It's just there most of the time, feels a lot like how a stressed joint feels (to me at least), which is to say, mild and bearable but has an accumulative effect over time, a bit like the way noise can be ignored if you hear it for a short while less so once you realize you're stuck with it for 24 hours.
