<s>[INST] Hi, my girlfriend accidentally hit her head against a handle of the top compartment of the fridge as she rose up. Now she is experiencing throbbing pain at the top of her head that is quite unbearable. Is it a concussion or an internal swelling? And what can be done to rectify the problem? [/INST] His am Chat Doctor. It is very unlikely that there is a very severe injury. So do relax. However, headache after the head injury should not be left untreated. Ideally, I would suggest testing a CT of the Brain, to make sure there is no internal bleeding. You may find that there is a swelling on the local site on the head where there has been the injury. This may also be a cause for the pain. I would suggest a painkiller like ibuprofen while you test the CT scan of the head. Do let us know the reports. Best of luck,  </s>
