[|Human|] Hello, My husband was just seen a week ago for a sinus infection and was given antibiotics. It is a week later and he has developed a small, hard,painful to the touch lump on the base of his head in the back on the right side. When he first noticed this he also had a bad headache with but took some aspirin and now does nit have the headache but still has the soreness. What could it be?
[|AI|]  Welcome to Chat Doctor .1. You already had a course of antibiotics, it seems for me its healing stage, and you need to wait for day 4-5, if not then need to examine. 2. Generally carbuncle/fur uncle are seen with pus discharge.3. As a precaution you need to maintain personnel hygiene and cleaning the area with the antiseptic liquids twice a day, and do not scratch the area as it delays the healing process. 4. I would recommend waiting and see - it should heel. Anything to ask ? Do not hesitate. Thank you.
