Constant Cough and Tickle in Throat

Patient: I had a cold about a month ago, but I’m still coughing, I have a tickle in my throat, I have mucus in my throat but am not coughing it out, I’m constantly clearing my throat. I haven’t really taken any medicine for it. It’s getting really annoying. It seems to get worse when I’m out of breath from exercising. Whats going on?

Symptoms: Coughing, tickle in throat, mucus
