Re: Can chlorine cause cold symptoms?
Yes, chlorine can cause sinus irritation, especially if your sinuses were somewhat irritated before you got into the pool.
Chlorinated water can also cause problems for people with inner ear disorders such as vestibular neuritis or ETD.
If you had a fever, chances are, this was a viral problem, and not an allergy issue. You will see that most people here (myself included) who have debilitating allergy problems, don't generally run fevers, even when there is a bacterial infection of the sinuses.
I think you are safe to swim.
