Thanks for writing your query.
After reading your post, it seems that you are having drug allergy
due to the antibiotic.
You should stop the medicine you are taking and you should consult your treating doctor for switching over to some other medicine for sinus infection
It is not necessary that if you have taken any medicine before, it will not cause allergy.
You should take some antiallegry like Fexofenadine
120 mg. This will also help in your sinus infection.
Take any medicine uder medical supervision only.
I hope this is helpful to you.
