Well I Hurt My Arm At Work, First I Thought

well I hurt my arm at work, first I thought I hit my elbow then couple weeks went by and there is a spot on my elbow that I touch and it hurts bad, if I touch my thumb to my pinky or ring finger its really painful. So its been over 2 months and nothings getting better, but when I move my hand in a certain way or make a fist my elbow hurts. I took 12 days off and it didn't get better.
