Thanks for coming to HCM. Do you have cold, running nose or fever? You symptoms are likely due to sinus infection
though it can be due tooth ache
or nearby soft tissue infection
. You can take over-the-counter preparation of paracetamol+caffeine combination 3 times a day, and menthol steam inhalation. But if you don't get relief in few hours, or develop fever, visit your ENT specialist
or local doctor.
Hope you get better soon!
