crickey I'm having a real worry day!

are tonsils supposed to be the same size? Or can they differ.
The one on the right size is possibly twice the length as the one on the left. it is also a bit prickly/ itchy/ red.- maybe this could be due to me always looking at it? It is roughly the same size in width, but as i said above its twice the length.
I have searched the web and scared myself crazy. Maybe it has aways been this size?
