How To Overcome The Nonstop Burning Of My Lungs?

Hi, I m Elise. I went to ER last night. After a steroid shot, keflex shot, 2 Zithromax pills and a breathing treatment, I was released with a script of Zithromax. I m coughing a lot, sometimes dry cough/sometimes it s bright green phlegm. I understand a cough suppressant is not ideal for a pneumonia patient, but is there ANYTHING I can take that will make my lungs stop the nonstop burning? I ve been taking OTC Ibuprofen and Tylenol for this roller coaster fever. I have taken so many OTC meds that I can t remember them all. I m in quite a bit of pain. My throat is raw and burns (tested negative for strep throat). What can I do to make all this burning & body aches stop? Thank you so much.
