I hope you make a full recovery. I have only had one serious crash in my 50 years of cycling and it was a pretty bad head injury. I was wearing a helmet and the attending physician was shocked that I had not suffered a concussion. I broke my facial bones in 5 places , including the orbital bone, but they did two MRI’s and no concussion. I was off the bike for 12 weeks. The most painful part of the whole ordeal was a broken left hand. I was only going 12mph and I got messed up so now I watch my downhill speeds. I used to love hitting speeds of 30mph+ but no more.
