Hello! So I was playing basketball 3 weeks ago. I took a hit hard while setting a screen, I had no pain but what I believe is the ac joint had a very weird sensation. Almost a letting go or loosening sensation. It didn’t hurt at the time, it didn’t hurt that night or even the next morning. The only time it started to hurt significant was 2 days later, after I did a hard shoulder day in the gym. The pain has since lingered for 3 weeks, slowly getting better but flares up if I try anything in the gym. Any ideas? The pain is not only in the ac joint by also can be sharp where the chest meets the humerus. No med insurance, getting Medicaid soon. Thank you so much! 28M 5’8.5” 170lbs
