What causes your tonsils to become swollen?

Answer by  riles14 (20)

Tonsils are often removed in childhood to prevent further problems. Most of the time the problem is acute and about 50% of the time there will be an infection of a B haemolytic steptococcus. The other 50% are viral and will go away with rest and lots of fluids.

Swollen tonsils do not necessarily indicate an infection, although they certain may. The common cold is commonly accompanied by swollen tonsils, whether or not a sore throat is present. Allergies may also cause swollen tonsils.

If you still have your tonsils a sore throat can make them become swollen, in my case I had Strep a lot of times and had to have them removed.

Your tonsils could have an infection or it could be just a cold. I would think sinus infections could make your tonsils very swollen.Really the main factor would be you having an infection of some sort.
