Yup I know that feeling. Everyone these past few days are wondering why i feel so crummy again. Sick of answering the question. People just dont seem to understand that a concussion is brain trauma of some sort depending on the severity. For example myself, a lot of people are confused as to why Im back at step one after four months. I was confused too. Now I know, plain and simple I over did it before I was fully healed and downplayed the severity of this kind of injury. Now im paying for it dearly.
