Ok, so about 2 weeks ago I started having a wheezing cough. A few days later i had a fever of 100.6. The next day the right side of my throat started swelling up and started hurting. Now that all has went away except for my cough and today I coughed up foamy stuff but I didn't get to see it because I spit it out of the window of my car. Can someone please tell me what this is I am kinda scared.
