I'm really worried about my dad. He had COVID recently and now the doctor mentioned that he has some kind of fistula in his left lung. I'm not sure what this means for his recovery or his health in general. Could you explain what a fistula in the lung is and how serious it might be? Is it something that happens because of COVID infections, and what kind of treatment should he expect?

Hey, I've been smoking about 10-12 cigarettes a day and lately I'm noticing some worrying things. There's a persistent pain in my throat and sometimes in my chest too. I'm also dealing with a sore throat alongside a coughing issue that's not going away. Could you suggest what might be going on or what I should do about it?

To help with the pain in your throat and chest, as well as the sore throat and coughing, I recommend you try using lozenges containing benzocaine for throat pain relief. Additionally, you can use cough syrup containing dextromethorphan to help with the cough. It is important to reduce or quit smoking to improve your symptoms and overall health.
