Hi Thank you for asking HCM I have gone through your query.Your problem is most likely upper respiratory passage infection.It can be viral or bacterial or viral superimposed with bacterial.In case of viral only symptomatic treatment is necessary.I usually give antihistamines like levocetirizine anti inflammatory like nimusulide, nasal deconesants like xylometazoline nasal spray and vitamin C.If there is bacterial infection i advise antibiotics like azithromycin or Co-amoxiclav. You can finish your levaquin dose as you are on it If your tongue is still sore steroids like kenacort application may help.Do warm saline gargle.Take warm chicken soup with pepper and tea with lemon.Hope this may help you. Let me know if anything not clear. Thanks.
