### input:
My 17 year old son had a head injury on the left side of his head that resulted in a subdural hemotoma on 9/6. The nuerosurgeon s operated and removed the hemotoma and also fixed a severe skull fracture , put in titanium plates and screws. Son has some blood and a small blood clot on the right side of his brain due to the brain ricochet from his fall, they did not treat that. He was released from the hospital on 9/12. He was released back to school on 9/24; however, he complains of dizziness to the point of feeling like he is going to pass out when reading and complains of a thumping in his head on the left side all leading to severe headaches. No nausea as he was having before with the immediate issues with the head injury. His follow up appointment is not until 10/15 due to some new hospital scheduling system (he was supposed to have a follow up in 2 weeks). At what point should I consider his complaints normal or consider them more serious requiring an emergency visit to the hospital?

### output:

Hello thanks for choosing Chat Doctor As he had a head injury just about a month back I think he could have rested for at least 4 weeks before putting him to mental stress. He should avoid any kind of stress for a few more weeks and let the brain recuperate. The following are the danger signs and look out for them 1) seizures / fits2) headache followed by vomiting 3) Severe unbearable headache (which he describes typically as "worst headache he has ever experienced")4) loss of consciousness5) periods of loss of memory 6) any neurological deficit (unable to move his limbs / weakness of limbs) All of these are emergency situations and require immediate treatment
