3 days ago I had a 3kg bag drop onto my head from about 1 metre. Since then I have had a non stop headache, vomiting, constantly feel dizzy and this morning pasted out while vomiting for approximately 10min. I am having trouble with talking to people and can’t look up at them while talking due to light making the headache worse. I have seen my gp all he said was to basically cheer up and I will feel better straight away. I have not been able to keep down any liquid or food since it happened. When it first happened I lost consciousness. I was taken to hospital but all they did was have me stand up and move my head told me I had a concussion and let me go home. My neck has been hurting non stop and moving my head makes me feel more dizzy. I also feel like there is someone pushing on the back of my head non stop too
