Hi and welcome,
Sorry i've not responded sooner, it's summer holidays over my side of the world and i've just got back online...
Mild tingling in your abdomen is pretty vague symptom wise, in a women it could be many different things eg bowel, ovarian, bladder etc, its unlikely to be anything serious if that's all you experience and unlikely to be a sign of a neurological condition like MS. I'm sure by now you've seen your GP and have a much better idea of what it's more likely to be....
Hope that helps.....JJ
Supermum_ms can you please advise
