Having played offensive and defensive line in footbal for a number of years, I've broken a few bones. Fingers, especially. An easy way to tell is to apply compression pressure (slight) along the length of the bone.

Example: If you think you broke your forearm, grab your wrist and push back towards your elbow.

If its a fracture, you will be in CRAZY PAIN even if you spply slight pressure. If there is little to no difference in pain, you likely have a deep bruise, which is nnothing to deminish. In any case, sling the thing and go to a free clinic.
