I was recently diagnosed with MS. I have been tasting blood in my mouth on and off for a month or so. I have told drs I've seen, but not getting any answers! Do you have any suggestions? Was told 1st MRI said possible brain tumor, but 2nd MRI dr said no. Am concerned. Also getting bad headaches too. Not sure if stress related or not. Any suggestions would be nice. Is the taste of blood something I should be worried about??? Because I am, but don't want to stress over nothing. Is this a possible symptom of MS?
