When I was visiting family friends I had a fall and bumped the left hand side of my forhead. I do not remember much of the rest of the evening. This morning on my way home I had a random nose bleed. today at work my colleagues told me I was repeating what I had already said earlier. I had no recollection of previously saying the things I was saying. Tonight I feel out of sort but feel very tired. should I visit the local hospital?
