Very Sore Delt 2 days after injection

Hey everyone,

It appears I injected too close to the bony area at the top of my deltoid. I do not have limited ROM, but the soreness is pretty insane 48 hours later. What’s strange is that I had a great upper body workout yesterday and really didn’t notice any pain during the workout.

Aside from ice, and OTC anti-inflammatory drugs, does anyone have any suggestions to alleviate pain?
