I have had extensive training in the proper care and extremities adjusting for all of the joints of your arms and legs.  It is quite common, especially if you are active, that you will cause injure and stress these joints.  If you work at a computer, you may also have joint problems in the elbows and wrists from using a mouse and keyboard.  I have special training on how to test and adjust all of these joints and how to balance the muscles that support them.
