How long is it safe to keep a pulse oximeter on my finger? I've noticed that when I leave it on for a while, the readings sometimes start to drop. Is this something to be concerned about?

I'm really worried because I've been told that my pleural effusion is due to TB. Is this type of TB something others can catch from me? Also, how long does it typically take to get better from this?

Ive been dealing with this dry cough for the last 20 days and even after taking some medicines, it just wont go away. Im really worried and unsure what to do next. Could you give me some advice or suggest what might be going on?

Persistent dry cough may require a different approach. You can try taking Benadryl (Diphenhydramine) 25mg every 6 hours as needed for cough. Additionally, you can use Robitussin DM (Dextromethorphan and Guaifenesin) 10ml every 4-6 hours as needed for cough. Make sure to stay hydrated and consider using a humidifier to help soothe your throat.
