So these occurred when I helped move a 600lb dresser. We set it down part way through moving it, and my arms started cramping up bad from burning all of the potassium out of my system.
The spots first appeared blue like the veins you see in your arms, but then after 15 minutes, they became red. They are now currently very sore, and they look like deep bruises. They are also swollen. Each spot you see in the picture that looks like a bruise is raised a 1/4 inch or more, like a goose egg you would get from a blow to the head.
