I have described the pain to the doc as a lava flow that starts as a pool at my shoulder and moves down to my hand, depending on how bad I ticked it off. The shoulder and arm always burn, but it turns to lava when angry. The normal burning, funny how the burn is even remotely considered normal, is usually accompanied with a feeling of pressure, like a constant band around the area. The doc kind of looks at me funny when I explain it, but I think it is a fitting description.
