Because your shoulder is such a complex joint, any inflammation can result in an impingement of the muscle resulting in more damage being done as you continue to use it.
It is important to stop if your shoulder becomes painful when exercising. In order to be effective this may well mean some changes to your day-to-day routine.
Shoulder injury exercises tend to be quite simple exercises that can easily be done at home as they do not require specialist equipment.
If you are anything like I was when I tore my rotator cuff, you are thinking of ways to avoid exercise, not how to try to start a new routine. Any pain caused by a rotator cuff problem is almost certainly the result of inflammation of the muscles and tendons.
While you are resting the muscles, treat the inflammation with non-steroidal anti-inflammatory drugs to bring down any internal swelling.
First order of the day is proper rest. This will in turn help to improve your range of movement. This in turn will help to alleviate the pain.
Rather than buying a set of small weights you can substitute tins of food for weights. These will be exercises that use little or no weight or resistance focusing on control and flexibility as well as on strengthening the rotator cuff.
Rotator cuff problems can start in a number of different ways, whether it is a sports-related injury, from an accident or just through getting older.
You can also use ice packs to help with inflammation once the joint has stopped being so painful and range of movement has improved you will need to do some shoulder injury exercises to strengthen the injured muscles and stabilize the joint.
If you have managed to damage your rotator cuff then exercise is going to feature somewhere in the recovery process. They can also vary from tendonitis and shoulder impingement up to a full thickness tear, but what they all have in common is that they all involve the rotator cuff and they are all potentially very painful. The pain is often an indicator that more damage is being done to your rotator cuff so it is essential to avoid painful movements.
It is important to listen to the messages that your body is giving you. If your work necessitates painful movement then you need to either change the way that you work or if this is not possible it may be that you need some time off work.
You will tend to start with gentle stretching exercises to help to avoid further injury before moving on to strengthening exercises. This means that the first two priorities for any shoulder injury are to rest the shoulder properly and treat the inflammation in that order.
