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?
Shit happens and it will get worse. Let me join the others in welcoming you to middle age.
Highly recommend mobility and strength exercises for your trouble spots. Make it strong and it's less likely to blow up on you from mundane normal activities.
Personal anecdote: I have a shitty back and I had to start PT and exercises bc I can't be laid up an entire week from putting fruit down on the kitchen counter again
