if your doctor's appointment is days away I'd take the chance of going to the ER before . I had a flare last month doctor's appointment wasn't until next week. I was able to start the dose of steroids and get an MRI at the hospital as they admitted me . Thank God I recognized the symptoms ahead of time and I had coworkers that understood the difference in my walk and talk . Don't ever prolong it

I, also have been through this with the slurred Speech. For Me it passes and comes back when I am tired or Over did things.

I ended up going to the er today.... after speaking to the neurologist they think I am having a flare up. They gave me steroids to take and said I should notice a difference within a day or 2.

New or old symptom lasting 24 hours or longer could mean a flare. New lesions don't light up forever, I think an MRI with enhancement can only catch the active lesion for 2-3 weeks, than it just shows up as inactive. The ER would likely not do an MRI, nor treat the flare with steroids and would probably just send you home and tell you to contact your neurologist. They may check you out for a stroke however. If your neurologist thinks you are having a flare, he will likely send you in for an MRI.

I took speech and cognitive therapy because it was bothering me so bad. I also have swallowing issues because of a weak tongue which is the cause of my speech. It gets worse when i'm fatigued or excited. Thre worst thing for me is having someone interrupt me or finish my sentence because i'm struggling to get it out. Sometimes I'll spit out words that don't belong, simply because i'm trying to go to fast. I've learned to slow down on my approach, and it's alot less stressful for me.... good luck
