I have a sinus infection and I went to the doctor last Thursday. He prescribed amoxicillin and a flonase spray. He also gave me a nasal steroid shot which he said would help me breathe. 24 hours later I couldn t smell or taste anything. It s been 6 days and I still can t smell or taste,,, and I don t think it s my congestion that s doing this because my nose is clear and I m not stuffed anyway. So, my question is can this be a side effect of the shot?
