I got angry and hit something about 2 hours ago, and my knuckle by my ring finger has a 3/4 in. gash in it and it hurts so bad when I have to move it open and close motion hurts the worst. Also, half way up my arm it hurts, and is swollen a little above my wrist. The whole area in general is swelling now, what should I do? It is 35 miles to the nearest ER, and I have two small children sleeping now. I dont know what to do about it. Should I wait for the ER tomorrow, or go now, or do I even need to go period. It really hurts.
