I hate to disagree with the doctor, however I have MS and experience this every time I have a flare up. The spots are the size of your finger tip usaully last 3 to 4 days. The soft spot seem to get deeper by 2 day, I always have pain in my body that accompany, being typical to MS it will be in alittle different area everytime. The headaches are terrible, many times I have had to go to the emergency room, they give me a shot of toradol, which is a strong Ibuprofin. Durning these times I have a really hard time concetrating, I just refer to them as my stupid spots. I recently participated in clinic study with Tovaxin, I had several MRI and none showed that I had turmors. Hope this helped you.
