Shoulder pain can be caused by a wide variety of different conditions and events, but the vast majority fall into these categories:
- Shoulder impingement
- Shoulder instability
- Improper Shoulder motion/functional imbalance
Often shoulder pain is caused by an imbalance within the shoulder muscles. When we train and workout we are constantly using the big prime movers of the shoulder joint like the bicep, triceps and deltoid. This causes the rotator cuff to become relatively weak in relation to the very strong bicep, triceps and deltoid muscles. The purpose of the rotator cuff is to give the shoulder stability and tell the brain where your shoulder is in relation to the rest of your body. When the rotator cuff muscles become weak they do not stabilize the shoulder properly and this will cause damage and inflammation to the joint resulting in pain.
