After tonsillectomy!

Hi guys, I just had tonsillectomy about 2 weeks ago. The first week during my recovery bad breath is gone(I noticed people didn’t touch their nose while talking to me) but the second week I feel like it came back right away. I can see people start touching their nose while they are talking to me and look at me weird.

I’m so lost right now😔 I did everything I could. I had sinus surgery, dentist said my teeth are fine but I still have acid reflux from time to time.

But I just don’t understand how come bb is gone during the first week that I’m taking antibiotics and when I stoped it came back right away.

Ps. I only eat ice-cream and protein shakes during the first week recovery. (Sorry for my English)
