NO. NOT UNLESS YOU ARE ON ONE OF THE MEDICATIONS THAT THE SIDE EFFECTS ARE FLU LIKE SYMPTOMS. I DON'T KNOW HOW LONG YOU HAVE HAD MS BUT IF YOU'RE RUNNING A FEVER MUCH AND IT'S NOT A SIDE EFFECT OF YOUR MED, THEN YOU NEED TO SEE YOUR NEUROLOGIST. MS IS NOTHING TO MESS WITH. YOU MIGHT HAVE SOME KIND OF INFECTION. I DON'T KNOW HOW LONG YOU'VE BEEN RUNNING A FEVER. YOU NEED TO SEE YOUR NEURO. THE REASON I KNOW YOU DON'T RUN A FEVER IS I HAVE MS AND HAVE BEEN DIAGNOSED FOR OVER A YEAR.
I have had MS for 30 years and have never had a fever due to my MS. I would definitely check with your doctor.
Sounds more like possible lymes disease or possibly spider bite -- any history of a tick bite or spider bite? Sometimes those things initiate multiple sclerosis, I understand. I'm not an M.D., just doing some research on this.
