Head Racquetball Shoes My Arm And Head Are Freaking Out. What Should I Do?

My arm and head are freaking out. What should I do? - head racquetball shoes

My arm was hanging by my side day, and when I try to lift it, it hurts like crazy. So today I racquetball on the head with a bat made by someone mph at 100. And now I can not head to the left, if I want to scream with pain. Besides the guy who made me hit my head and my shoulder and the other arm was sore. What should I do? Should I see a doctor? Should I ignore it? Should I beat the man who beat me? What should I do?
