re: Pains that get better as body heats up during exercise

I've had tendonitis and it acted like that. According to the physical therapist, increased blood flow can help to relieve the pain. Hence exercising "loosening" it up and it feeling a little better. But at the same time, it's not fixing the issue and could even continue making it worse. Long runs would hurt at the beginning, feel good once I warmed up, then back to pain again once I pushed it a little too far. Just never knew when that "too far" line would pop up. I'm no doctor, but in my very limited experience, it points to some sort of inflammation.
