I had a sinus infection and about 7 days ago I developed Tinnitus in only my left ear. I started getting all panicky because I am 17, and I felt like I was too young to even get it! I read about a lot of information and I know that I can deal with it if I have it permanently! Well after my sinuses cleared up, the ringing got less but the background sound is noticeable at night, but I was very very happy. Now I am paranoid about taking any medicines that might spike it up again such as pain killers. My sinuses have completely cleared but my throat feels itchy all the time, causing me to cough a lot. I went to the doctor to check for ear infections, my sinuses and all that. He said that nothing was wrong and he prescribed me "Guaiatussin" for my cough, I wanted to make sure if its safe but ended up finding no information about it online. Have you guys ever taken this medicine or know anything about it? Also if you have any OTC medicines that can work with tinnitus please tell me! Thank you!
