I been practicing level 1 for about 2 months now and just this past week have experienced some very odd and uncomfortable pains - in both shoulders, enough so that I have suspended some of the active excerises because I am in pain and I felt that it might have been the exersise that brought them on. At firt is was just the left shoulder; the pain would sort of move around from the scapula area and then to the outside and back or both. Then a day later a similar pain took up residence in my right shoulder - both side at once. Sometimes it feels like the joint and at other times it feels like a tendon/ligament or muscle. Moving my arms above my head or reaching is painful. Very strange! Does anyone out there have a clue what this might be and what to do about it.At the age of 55 one might expect some arthritis in those joints, but all of a sudden?
