Is this all normal after Rhinoplasty?

I did Rhinoplasty and l'm now 3 weeks post op, my lips are very dry, dry skin, my eyes and face looks extremely tired, very hallow eyes and a week later after surgery when I stopped my medications (steroids for my swelling, clindamycin and pain meds) I have been having bad diarrhea since then until today and crazy allergies basically sneezing all day. Is this all normal?
