I received a rather hard impact to the head with a shinai (kendo sword) without armor. I have since noticed a depression within the area of the impact. There's pain around the area though it's actually greater around the depression with very little inside it. Pain only arises when I touch, rub, poke, etc the area. A painful tinge is felt if I turn my head completely to the left side (injury is on left of head above the temporal bone. About an inch above eye in terms of location, but close to ear.) The pain when I turn my head is actually not where the depression is. I really need a very good reason to go to a hospital for this because I can't take off from classes or work and both basically dominate my days. I'm a 3-4 yr practioner of kendo, kenjutsu and Muay Thai; this was a REALLY stupid move on my part. It's the result of random unarmored foolishness among friends; I asked for no head shots and my opponent apparently disagreed. Gr. I also feel tremendously stuffed up, but I have a dreadful cold at the moment so that would explain the feeling in my ears and such.
