Dr Bernadette Carr answers your questions on osteoarthritis and mumps

Q. I have always led an active lifestyle and enjoy jogging to keep fit. Recently I have begun to have very bad pains in my hip when I get up in the morning and when I rest at night. 

I am only 56 I am worried I might have arthritis.

A. Osteoarthritis is inflammation of the joints often caused by overuse or wear and tear. It is the most common form of arthritis and its frequency increases with age.
