Hi, i seem to have hurt my shoulder at the gym, doing bench press about 2 weeks ago. it hurts slightly when i wake up but the pain goes away. there is a bunp on my shoulder, where the ac joint is, looks like the bone is sticking out. any advice?

AC joint injury: Sounds like an AC joint sprain or mild separation. This can be easily diagnosed with an x-ray and physical exam. An orthopedic surgeon or sports medicine doc should be able to diagnose and treat you. Low grade injuries are usually treated with rest, ice, and anti-inflammatories. Sometimes injections or even surgery are indicated. Best to have it looked at.
