Csection recovery questions! Help!

Hi for the ladies who had a csection...

I had one 4 days ago and ever since then I have been SO congested. Phlegm in the throat, stuffy nose! I always want to cough but I can’t find a comfortable way to do so :(

I also feel like I can’t lay flat on my back yet either like it’s harder to breathe?

Anyone else?

And as far as healing are any of you ladies covering your wound daily?

No one in my family has ever had a csection so I’m a little on my own on this one 😬
