I have been having left side pain for over a year now. I have had MRI's and CT scans done. They say they don't see anything. It's a constant pain, hurts to itch, sometimes touch. Sometimes it starts from the back of my head and all the way down to my shoulder, arm,wrist, knee, leg, and foot. My hand swells and my back hurts. I even works to walk. I am tired all the time, even if I get six hours of sleep.The pain does not go away.It is on a daily basis. Some please help me!!!!!!!!
