Hey guys, I am a flexible guy, though in the morning I feel stiff as fuck, when i tuck my chin in the chest, especially in seated forward bending (in the morning) my mid-upper back really gets pulledd and hurts, at that point it's not just a stretch but it's pain no matter how little I do it. I never been able to stretch that part and I have no idea why I feel this. It's why I avoid stretching in the morning. I thought of doing acupuncture for it. What do you guys think of it?
