<s>[INST] Hello doctor, I am a 29-year-old male and I have headaches with sinus infection symptoms. There is a scar inside my nose. The headaches are on one side of my head. It started about one week ago. I had this scar inside my nose about nine months ago. Also, the headache started about nine months ago too when I started sports. There was nothing until then. Please help. [/INST] Hello. The headaches due to sinus infection are most likely to be more severe in the morning and when you lean forward. Also, you will have tender bones of the face. So do you have any of these symptoms?  It is treated with a course of antibiotics for one month like Augmentin (Amoxicillin and Potassium Clavulanate) 1 g every 12 hours plus Paracetamol 1000 mg three times per day. Consult your specialist doctor, discuss with him or her and with their consent take the medicines. If you suspect any complications or in order to classify the severity of the condition, a CT (computed tomography) of the paranasal sinuses is required.
