This happens mainly on my torso but has been known on upper arms and legs. If I knock myself or anybody touches me or if I have an itch and scratch it I am in pain for almost 10 minutes. It is a severe pain. It kind of makes me squirm to try and move away from it but nothing works. It just fades after 5-10 minutes. So does everyone have this? Should I be worried? I've had it for a long time. It's not new. I have developed a painful lump at the bottom of my right ribs which I am going to see the doctor about. Is it worth mentioning the other pain? I feel a bit of an idiot describing it really
