My father has 57 years old. Form few months his getting heavy pain in right hand shoulder, his can't lifting anything by right hand and he was consultant the doctor in last month. The doctor said that the pain may be coming due to sugar level in the body. (sugar test is conducted in the past. The reports shows that sugar level is done in the body. Some days he had sugar pills and stopped). The doctor gave tablets to the shoulder pain for a period of 20 days but the tablets are not working anything. The pain is going like that only. And may be increasing that pain. Why it is paining. What should I do for this type of pains.
