About a week ago I started to get a heavy dull pain in my upper right arm. I have felt gently around my arm to see if there are any lumps. There appears to be nothing, no bruising, yet if I press a certian spot it is very painful. The pain also seems to have moved from one pressure point to another, ie: when I press where it first started it is not intensely painful. I also can't remember bumping into anything, it is even painful to turn the steering wheel of my car. As I write there if a dull throb. What can cause this?
