I suffered a concussion on june 29th w/ no loss of concussion, at least i think, i was alone. I did not vomit, i was dazed and had blurred vision immediately after and had a headache for 3 days. I went to the er and had a normal ct scan and no broken bones. I had been symptom free for two weeks until i suffered a 2nd concussion with a loss of consciousness on July 13th. I do not remember a thing, i just woke up in the er and had a headache for one week. I have some tenderness on the side of my head which im sure is just bruising but i have had no headaches today. My 2nd trip to the er also resulted in a normal ct scan and no broken bones. Before all this happened I scheduled a surfing trip for a week which starts on Aug. 1st. Basically my question is if i remain symptom free for the rest of the week can i go surfing.
