Thanks for writing your query.
It seems that you are having infectiion in the upper respiratory tract
You should get yorself examined by an ENT specialist
White bumps can be due to tonsillar stones/infetcion of the tonsils. Tonsillar stone can result in pain in throat during swallowing and also in foul smelling breath. If present, they can be removed by your ENT doctor.
You should get a throat swab culture done along with Complete Blood Count
You can take pain killer like Ibuprofen
one tablet twice a day after meals along with antacid
for relief of pain. Antibiotic can be added according to the culture/senstivity reports. Antihistamines along with decongestants will also be helpful for relief of your symptoms.
I hope this is helpful to you.
