I am 64 years old. A diabetic for more than 10 yrs, but under control with medicines. Latest HBA1C is 6.3During the last two months, I feel pain in myright hand -between shoulder and knee- and also in the shoulder whenever I lift the hand or turn it. With muscle relaxant tablets and/or with ointment massage (moov or Himami) I get relief considerably. But the discomfort returns from time to time. Can you kindly advice on further course?
