Hello there! I hit my head very hard 8 days ago. I was standing up and bent my upper body over my knees with great force. There was a glass door that escaped my vision and I slammed the RIGHT side of my head on the glass. When this happened, I literally felt my brain hit the back LEFT side of my head from the velocity of the impact. I did not lose consciousness, but I sure was dizzy. About two days after the incident, I noticed a sharp pain on the left side of my neck; it has since radiated to my upper-middle back, on the left side only. I have had back issues before and did physical therapy. I just want to know if there could be bleeding from this. Thank You
