I recently suffered a subdural hematoma to left temporal area after hitting my head post falling from a bike event though I was wearing a helmet. I spent a day an half in the ICU and the released in two days. I am very active, triathlete and Ironman competitor. What is a reasonable time to wait to resurme my normal activities such as running, biking and swiming? I still feel some pressure on the area of my head but no unbearable pain, just a sensation. I so far have no problems with my memory, I did though when I fell as I could not recall what happened that caused the fall but able to remember everything that I did before.
