Biceps tendinitis is a problem with a tendon in the shoulder. The area where the upper arm bone meets the shoulder joint becomes swollen. This can be caused by aging or repetitive movements like throwing.
Symptoms include shoulder pain and limited range of motion. These are most noticeable when doing things like lifting or reaching behind your back. Treatment includes icing the shoulder and taking pain medications. Simple stretching exercises might also help.
If the pain doesn’t go away after a few weeks, your doctor might suggest steroid shots. Ultrasound imaging can help make sure the shot is given in exactly the right spot.
