Was not always the case. Never had issues until my 20s. First time I noticed it was of course after the long stretch of little physical activity when I was in university and working almost full time on top of that. So 5 years. Then when I tried to get back to it, it was excruciating after every workout. I noticed something was out of whack when my 350+lb friend of mine who was trying to get in shape at the time, who had never worked out in his life seemed to be recovering faster than I was after our workouts.
Will take a look into the fibromyalgia thing. Not entirely convinced because if I'm not putting in workouts, I'm not aching at all, nor any of the other symptoms other than stiffness. I'm always stiff but I chalk that up to 10 hours a day of office work. My flexibility is admittedly TERRIBLE these days. I feel like I'm being held together by steel cable when I try to stretch to improve flexibility.
But it also seems that the treatment is more exercise and OTC painkillers, which is basically what I've been doing (plus plenty of weed of course). So do I just suck it up for longer this time??
