Replying to Concusion question

so last night was my season opener at my home mountain. i was on my brand new fujas and was ripping them around, testing them out. So i was FLYING down at full speed, popped it switch over a creek, rode out like 10 feet, went to turn, caught an isdise edge and spiked my head in the ground. good thing that i had a helmet on. My buddy brought me home early because I was so shitty. My head is pounding right now, and i was puking when i got home. I'm tired all the time and have been sleeping all day. Does that sound like a concusion?
