I started having these sensations on my head a few months ago...itching. A spot at a time but all over my head. It made me think, jeez, is my hair filthy--no it isn't, so what's going on with my scalp?!! I've just been a scratchin not even thinking it was an MS thing!! I guess because it was a spot here a spot there, jumping from place to place as opposed to a singular area having something weird going on, caused me to not think it was possibly one more thing to add to the MS list!! I feel better knowing tho, that I probably don't have bugs!
