Hi--I have had a cold for 11 days and one 3-4 weeks ago as well. I feel like I m in a tunnel...heavy head...I have a productive cough but can only swallow it, and I have been blowing nose for a week. I sound very nasal and feel poorly. The mucous has been mostly clear, some light yellow and only a little darker a couple of times. As much as I have blown, I but don t feel like a lot of it is really coming out. My head is more sore on one side and in the back back of it as opposed to facial and eye pain. My ears sometimes squeak when I blow. Do you think I should get an antibiotic? THANK YOU.
