I'm really worried about my dad. He had an angioplasty 5 days ago and now he's got a fever, like 101F. His face and neck feel warm, but not his arms and legs. Plus, he's got a cough with white phlegm. I've been giving him paracetamol and he's taking lizolid and ceftum twice a day, like the doctor said. Is this something normal after such a procedure, or should I be concerned?

It is not uncommon to have a fever after a surgical procedure like angioplasty, but it is important to monitor it closely. The symptoms of fever and cough with white phlegm could indicate an infection. The medications you have mentioned are appropriate for such symptoms. Continue giving him paracetamol for fever. Additionally, ensure he completes the full course of antibiotics - lizolid and ceftum - as prescribed. Monitor his temperature regularly and if the fever persists or if he develops any new symptoms, please consult with his healthcare provider for further evaluation and management.
