Hi Sir, I fell down from my bed tonight. While I was sleeping, I accidentally came to the side of the bed and took a turn and I fell down. My bed is 3 feet tall. My floor is made of concrete and marble was attached to it so it is very hard. I got hurt in my head after I fall. It is paining a little bit. I took painkillers. Will that hurt in my head damage my brain? I am a student and I have much to read. Will the hurt in my head harm my brain? Will I loss my memory power?
