Dr Bernadette Carr answers your questions on shoulder pain and squinting

I was putting some boxes up into the attic last week and I think I may have injured my shoulder. I have pain in my shoulder with ‘pins and needles’ down into my arm to my little finger. Could I have tendonitis?

Shoulder pain is a common condition. As the symptoms you are experiencing occurred after a particular activity it is possible you have rotator cuff tendonitis. Tendonitis is an inflammation of a tendon that may be the result of an acute injury rather than long term degeneration from repetitive movements in either your work or sport.

A common form of shoulder pain, rotator cuff tendonitis is an inflammation of the tendons of the rotator cuff muscles. The onset can be sudden and painful, particularly if you try to lift your arms above your head. This condition is also known as impingement syndrome and painful arc syndrome.
