Hello,
Your friend is having facial swelling,
severe headache, joint pain and general weakness. Facial swelling could be due to
soft tissue injury or fracture of facial bone (mandible or maxillary bone). It needs evaluation by X-ray or CT face. He must consult emergency doctor for it. Severe headache, after fall, could be due to concussion, skull
bone fracture or intracranial bleed. It should not be ignored. It also needs emergency consultation.
Joint pain and general weakness are due to injury, lack of nutrition or water in body, fever due to injury. Overall, your friend needs
medical help. He will be advised CT head and face to find injuries. For treatment, he will be prescribed painkillers, antacids or few other medications depending upon his CT findings. Meanwhile, at home, you can ask him to take rest, drink plenty of fluids, avoid alcohol completely, take tab Diclofenac, tab Pantoprazole after prescription and apply ice pack at injury site.
Take care. Hope I have answered your question. Let me know if I can assist you further.
