<s>[INST] On Thursday morning I started with a sore throat that got progressively worse all day. By night I had 101 fever, a running nose and the throat was so painful I couldn t speak. I treated myself with Alkazelter Plus (which usually dries me up) and Nasacort (which usually alleviates sore throats cause by my allergies) and Advil for fever and aches. By yesterday morning the sore throat was gone, but replaced by thick phlegm in my nose and chest. The fever was gone. Since yesterday morning I have been treating with Musinex, hot compresses over Vicks vapor rub on my chest and bed rest. My phlegm is yellow & darkish green, from nose and chest and is so hard to bring up that I ve irritated my throat again. I don t want to take antibiotics if I don t need to. What do I have and what should I take? [/INST] Hi, I understand your concern.  You had self treated your symptoms of allergic sinusitis with lower respiratory tract infection with the usual Chat Doctor.  But it seems it was a severe allergic episode this time, which was secondarily infected by bacteria/viruses.  The occurrence of fever/thick green phlegm indicate deeper lung involvement. And in such condition you do need antibiotic.  Ideally antibiotic is selected after physical examination, blood counts & sputum culture & sensitivity test(if needful). If you are rarely taking antibiotics- you can try with-Tab Literal 400 mg twice a day, along with tab. Levocetrizine at bed time cough syrup containing bromelain. For minimum 5 days.  The duration of medication & antibiotics are better selected after assessing physical condition. So I would advise for consulting your doctor before you start with medicines.  With it, you can continue with rest, hot saline gargles, picks vapor inhalation, light nourishing food, avoiding allergens / cold/sour eatables.  Thanks. </s>
