Calling Doctor NSS STAT!

So i have had this cold for like 5 weeks but the last week, the symptoms have been stuffy nose and coughing up like globs of mucus. I cant take traditional cough medicine because i take prescribed medications that fuck with them. I use afrain (sp) which is like nasal solution that works like a charm and clears my nose up instantly for 12 hours, which cancels out the mucus coughing. Do you think I should see a doctor because i have had this cold so long or just wait it out.

i know people will ask more questions so ask away

thanks!
