The question is have is this. Yesterday while walking I fell into an uncovered hole near a drainage access, the fall took my left leg down about a foot before stopping it with blunt trauma to my shin and three abrasions to my right knee right knee from the concrete fill next to it. at the time I felt fine till i could get to the first aid kit in my car not far away, but as soon as I sat down, there wasn t much pain, but my head went numb and ears started to deafen me with ringing which caused me to feel very faint, but it only lasted about two minutes, be for I felt fine enough to walk again. Should I worry about this or am I fine?
