idk wtf I did but I woke up 2 days ago with this pain in my shoulder right inside where the shoulder itself meets my chest and man it hurts. It's so bad in the morning I can't lift my arm over my head. But as the day goes on (and taking some nsaids) it lessens a bit.
What did I do to myself?
Might be time to start doing yoga/pilates/martial arts stretches. I've entered one of these aging periods myself and yeah, sometimes I wake up absolutely bodied. But when I remember to do that physical stuff (reverse planks saved my lower back) it tends to settle down and things feel okay again. Reminds me, I've been slacking off. Probably gonna start feeling busted again soon.
