My dad has rotator cuff in his right shoulder and he always is in pain. However, the last couples of days the pain has been awful. I hate seeing him in pain and I feel helpless. I get depressed watching him feeling miserable. I call the doctor and he came a few hours ago. He gave him an injection of cortisone. The injection would cause him a temporary relief and it would last for a few months. At least I know he would sleep and feel better. After he went to bed, I went for my walk and now we can all have a good sleep.
