Hello, I was riding my bike on Saturday and got hit by a car... I was going pretty slow and so was the car, I hit head on, I fell on my bike and under my chin/jaw hit the bumper of the car, I have bruised legs and scratches and split open the bottom of my chin my jaw really hurt and was swollen it hurt to open and close it but more so to bite. It has gotten better with icing and ib profen. Today I feel really anxious, dizzy, feel nauseous, diarrhea (gross i m sorry) I had a smoothie and coffee so I m blaming that but could I have some kind of head trauma?
