Hi and thanks for the query,
Probably both of your ears are infected.
You are also suffering from sinusitis
hence you get pain whenever you bend down.
You can use any over the counter nasal decongestant like otrivin
You can follow instructions on the scrimp for using otrivin.
After putting the drops give a gap of ten minutes and do steam inhalation for 10 minutes.
Repeat the procedure 3 times daily for 5 days.
Otrivin helps to decongest your nose and helps drain your sinuses
It also helps to unclog the eustachian tubes which in turn helps to control the ear infection
Drink plenty of water and blow 2 balloons daily. It helps to open your eustachian tubes.
If you do not feel better in 2 more days then you have to go to the doctor.
Regards, Dr Kishori.
