I'm 24 years old male, from a few days ome side of my neck is swollen and i'm having pain/ discomfort in swallowing and speaking. today I checked with torch in the mirror I saw white ulcer type scratches on my throat and back side of tongue. I was a daily smoker and have left ciggerete 10 days ago. I've started taking antibiotic azithromycin daily since 2 days back, thinking it might be swollen lymph nodes because of some bacterial infection. But now i'm a little worried about it.
