Just found out I ruptured my eardrum

I have no idea how, and oddly enough I didn’t feel pain? I’ve been pretty sick for a week so I don’t know if the pain from that just kinda blended in our what, but a trip to urgent care last night confirmed I have a small hole in my left eardrum. I have a flight tomorrow, the doctor said I’m safe to fly since the damage is done.

However, I forgot to ask if I should wear earplugs on the flight. Is that necessary if it’s already ruptured?
