I took a spill last night and conked my head really good. My helmet cracked and I received 6 stitches on the left side of my head. I don't remember anything about the ride, not even starting it. The accident happened about 4 miles into the ride. I remember putting some chicken in the oven, and then nothing until being in the neuro unit at the hospital. My wife said that I was asking questions repeatedly and was very disoriented, and I don't remember any of that. The MRI was negative for any bleeds and xrays were negative for any fractures. I have road rash on the L side of my body and arm. I'm still having a lot of memory issues, but the doctor said that this was common for a severe concussion and should resolve in time. They kept me overnight for observation and sent me home today. I have no clue as to what happened. Someone called the paramedics, there were no witnesses, and I'm left wondering. Luckily there was a carry out on the corner and they secured my bike for me (supposedly it looks undamaged).This is scary folks....wear your helmet. I'd probably be dead now if I didn't. Sorry about the fragmented post. Anyone else experience something similar?
