I am allergic to dust mites, medication helped now problem has returned?

I am allergic to dust mites. And have been on Xolair for six months. My allergies went all away. And felt great for a year. No longer on Xolaire now. But I now have a throat infection (white infected tonsils), fever and cold like symptoms. And all my allergies (skin rashes all over my body) have come back. I don’t know what I should do?

I have had a severe sinus cold which has affected my sense of smell?

Hello doctor, 2 months ago I suffered from a severe head sinus cold for 2 weeks. After which i felt fine, but I started to lose my sense of smell. It began slowly but now is continuing and I am worried. I saw a doctor who said I had nose polyps and inflammation. what do you recommend I do. I don’t want to no longer be able to smell!
