While attempting to return a drop shot during a lawn tennis match, I rammed myself into the upper part of net made of hard wire. Both left and right arms (little below shoulders) were impacted directly, pained little bit initially but it subsided the same day. After couple of days, I saw the impacted area dark red because of blood clot but no pain. 5 days have past, situation is still the same. Does the clotted area become normal by itself? Again, no pain in moving the arms or otherwise until I touch the area, but that too very mild.
