Common Warning Signs for Multiple Sclerosis Common MS warning signs, I think if anybody is having something that maybe neurological that is just not right; it’s something you want to think about. Neurological symptoms can occur similarly in different diseases. So, just because you have one neurological symptom we can’t say “Oh, this is MS”. But it does mean that something may not be right and when I say neurological symptom, I mean blurred vision, some tingling, perhaps you’re chirping with one of your foot. So, I think that if all of the sudden you're noticing that things just don’t seem quite right, it's worth investigating with your doctor.
