i picked up a bad cold about 6 days ago, i was traveling by air so i thought it was important to get checked out, went to the md on day 2 he said it was just a bad virus and should pas on its own in a few days. i now have a bad sinus cold ear aches low fever of 100f, i cant sleep at night because as soon as i lay down i cant stop coughing, blood in nasil mucus, dark yellow hard mucus being coughed up and blown out in the early morning. do i need to see a md or will this pass on its own in time?
