I went to the doctor for a sinus infection/ear pressure. They gave me a flu shot and prescribed me sudogest, which I ve been taking as prescribed. It is not seeming to help and over the last 3 days I started coughing, causing a major pressure headache in my head. The ear pain has gone away, but I am now having pressure pains on the whole right side of my face, including the cough. I ve been on the sudogest all 3 days, but since my symptoms have morphed, I m wondering whether to stick with sudogest or switch it up?
