7 weeks post-op. I was a little sick and I saw my general practitioner. He prescribed me with augmentine and prednisone.

I'm 7 weeks post op I caught some kind of a flu and I was congested I saw my gp he prescribed me with augmentine and prednisone and told me to use some nasal spray according to him I have inflammation in my nose. My question is could the inflammation be from the surgery and I shouldn't take what prescribed me? I'm just worried I don't want to stuff up my nose. My surgeon is so hard to get in contact with because he is overseas I hope you guys can give me a little help?
