Hello,
Thanks for posting your query.

From the symptoms that you have described it can be rotator cuff tendonitis or shoulder impringement syndrome which causes irritation and inflammation of the rotator cuff and the bursa when doing overhead activity and hence pain.

Usually, there is enough room between the acromion and the rotator cuff so that the tendons slide easily underneath the acromion as the arm is raised. But each time the arm is raised, there is a bit of rubbing or pinching on the tendons and the bursa. With overuse, this can cause irritation and swelling of the bursa.

There are a group of muscles and tendons which form a covering around the head of your upper arm bone and attach it to your shoulder blade. This group is collectively called the rotator cuff muscles and from your symptoms the possibility of rotator cuff tendonitis is more likely. It causes local swelling and tenderness in the shoulder and initially it presents as minor pain but gradually it causes severe pain and loss of motion.

The other possibility is of osteoarthritis at your age.

You need to get an MRI scan done which is a more sensitive test for soft tissue and muscular injuries. An orthopedician is the best person to be consulted.

Here are some general treatment measures which you can follow:

1)     Provide complete rest and avoid overhead activities.

2)     Apply cold compresses and take some anti inflammatory pain killer after consulting your doctor.

If the symptoms are severe then after confirming the diagnosis by MRI, you may need steroid injections or surgical arthroscopic technique (kept as last resort).

Hope this answers your query.
