Hi Jabra Taweel,
Welcome to NeuroTalk.

Are you still having the fever and pain now?

Scroll down to Colloid Cyst on the pdf

If you're having such terrible pain and also a fever, I would be concerned about the build up of pressure.
I don't have a Colloid Cyst so I'm just going on what I do know and have read.
