uncomfortable pain from left shoulder blade over to shoulder but
Hello and welcome,
If pain is increasing rapidly, it's time to go in to be seen.
It's possible that there is nerve impingement, and given the numbness, it's time to have this evaluated.
NSAIDS such as ibuprofen or naproxen, which treat both inflammation and pain, might be appropriate, but first I think it would be important to see what it is that needs treating.
So... I recommend you go in now, to an urgent care or, if the pain is severe, an ER.
I hope this information helps.
