I agree with Cherie, dont screw around with infections. The doctor, if he's not your neuro, and hasnt had many MS patients, might not realize the seriousness of an MSer with an infection.

Do you have a fever? If you do, you might want to ask your doctor what to do to take care of that...(I know what to do, but it's practicing medicine without a license for anyone other than a doctor to suggest that you take anything for it, so ask your doctor. Sorry, my Medical Ethics class is being channeled thru me right now.)
