to be honest tests do probably need to be run. the second opinion always helps most times. get a bike helmet, get use to wearing it until your brain can heal up some, I'm no doctor but have had many head injuries. years with migraines because of them. the brain given the chance will heal it takes a very long time, i am not talking just a couple months either. try a year maybe more depending on the damage. i have on now looks like half an egg but is keeping me from damage. get looked at seriously that many hits can be daunting but they have great doctors at mayo clinics. have a blessed day and ill send a prayer for you too ========== sent.
