My dad has been suffering from sever pain in the shoulder for the last 2 months. We went to the doctor, she says it looks like tendonitis and will take 3 months at least. She gave some anti-inflamatory tablets and ointment, which did help a bit but even now he cannot lift his arm. Movement of the arm is very restricted. It is swollen a bit and feels very warm at night and also he gets severe cramps at night. He has been taking MSM and Vitamin C tablets for the last one week but we are yet to see any dramatic difference in his condition. AS it is his right hand, so day to day activties are really painful for him. Please advise what we should do. If Ted can suggest something that will be terrific. He is also taking 1-2 table spoons of ACV in 8 glasses of water and sips through out the day..
