Weird feeling in head.....

[Guest guest]

Has anybody had a strange lightheaded like feeling in their head

that makes it hard to concentrate. If so what helps get rid of it.

Also, how do you know if you have an infection? Is it possible to

have an infection without any fever.

Anybody have a tight feeling with tingling running down their arms?

Anybody feel like they are breathing out a chemical or something like it?

Thanks
