Sorry to hear about your problem. Before we can really help you, we need some more information about your injury.
1. What does the pain feel like, sharp / burning / constant ache
2. How long does the pain take to settle? Does it go away straight away following the activity, or does it linger for a few hours / days.
3. Are you doing a dumbell presses lying down? or military style seated? And what other activities (at gym or during the day) aggravate your pain?
4. Can you be more specific at your location of the pain. Is it on the front / side / back / top? try and give be as specific as you can.
5. Some quick tests
- Pain when you bring your arms to 90 degrees to the side holding a light weight? (few kgs) ? turn your thumbs down as far as you can, then back up as far as you can. ? does the pain change?
- Try the same test forwards, again alternating the position of your thumbs
- Put your hand behind your back, push hard into a wall. any pain?
- Can you touch the pain? Does pressing it make the pain change? Worse / Better?
If you can answer some of these questions it will help in diagnosing (although it will likely take a few more questions to narrow things down).
