How to stop shoulder pains
Rest your shoulder.
Often, but not always, the root cause of shoulder pain is simple overexertion-lifting things that are too heavy or lifting lighter loads too often. Stop the aggravating activity for at least a few days.
If your problem is work related, then if possible, talk to your boss about switching to a different activity. If the shoulder pain is exercise related, then you may be working out too aggressively or with bad form-consult with a personal trainer.
