Could skin conditions/allergies, eg urticaria, be a symptom and possibly part of the Prodrome of MS?

I and many people I know experienced chronic skin conditions such as urticaria (in my case brought about by heat or cold including exercise induced body temperature increase) long prior to being diagnosed. in my case this intermittent urticaria lasted about 3 years and then stopped and has never recurred. Should unexplained urticaria be a trigger for medical practitioners to be alerted to look for MS
