Can Vitamin B12 Deficiency, Cause Itchy And Swollen Welts?

I have been having periods of itching from different parts of my body, with no rash visible but when I give in to scratching I will have swollen welts and after awhile it will settle down and all go away, except when I itch to much I'll bruise myself.Help, what do I do? My doctor thinks it's simply a matter of B-12 deficiency.

Itching is not a manifestation of Vit B12 deficiency it usually manifest with neurological problem ,weakness , constipation etc .. As I understand it could be allergic in nature as such kind of feature are find in allergy due to some environmental cause . you need to consult dermatologist and undergone examination of your swelling .
