I wouldn't get discouraged until you know for sure the issue will be difficult to deal with. Some skeletal joints are complex. Ball and socket joints such as hips and shoulders have numerous layers of criss-crossing muscles and tendons to make possible rotary motions. Some of these muscles are very weak because they are seldom used. This weakness was evident to me by the very light weights (3 lbs.) prescribed to me for the exercises and the unusual position needed to work the effected muscles. As I said, tendonitis for me cleared up in days and it may well be the same for you.
