I have an overall feeling of fatigue. Sometimes, I feel a sharp pain between my shoulder blades; it s almost as if someone is twisting a knife in my left shoulder. I also have pain that moves up and down along my right side, from under my arm clear down to the hip. Sometimes I feel fine, but I have some kind of pain at least once a day. So far, the doctor has done an ekg but it came up negative. I tend to give up on searching for answers because I start to think that maybe the pains are phantom pains that come with aging, but I want to know exactly what could be causing these symptoms because they are very irritating and I want to get back to my life.
