Recked the morning of the first 1 am

I park ride at early hours" I hit the bowl at scate park" so people don't see me reck while I learn. And I may have been jumped. I don't remember what happened woke up later that day at home covered in blood. I just assumed that I recked but was brought to my attention it looked different. That it looked like I was hit on the side of my head. Spent the most the first in the hospital untill the second and now can not ride for a few more days
