Yes, this is a health concern. It seems like flu.
Do warm saline gargling with salt and warm water thrice daily. You can also try Betadine
mouth gargle thrice daily.
Take steam inhalation with karvol
plus inhalant capsules twice daily. Take over the counter available medicines like Tylenol
(500mg twice daily after food) and Zyrtec
(10mg at bedtime) for time being until you see your doctor tomorrow.
Get well soon.
