Multiple sclerosis causes a wide range of symptoms. That being said, some of the more common ones are extreme/abnormal fatigue, numbness/tingling, balance/coordination problems, muscle weakness, nerve pain, spasticity, tremors, blurred/double vision and vertigo.
Heat, infection and stress can worsen symptoms and/or trigger relapses.
So I try and stay cool and avoid illness as much as anyone can...still working on that last one. If anyone out there has a cure for stress, I am all ears!!! :-)
