Severe itching

I just started taking more vitamins and I was wondering if they may be the cause of my severe itching.  I am taking vitamin b6, vitamin b12, omega III, multiple with minerals and vitamin c, and vitamin d.  I started on these last week now I am itching all over my face, neck and arms, and its driving me crazy.  I have had chronic itch for several years, do not know why, but this itching is different.  My chronic itching is usually the bottom of my feet, my tail bone and calves.  I am open for any answers.

Hi,
      Itching skin can be due to various reasons like dry skin, dermatitis, hives, psoriasis or due to certain medical conditions like liver or kidney failure, anemia, thyroid problems or certain type of cancers. Certain drugs like antibiotics, antifungal and narcotics are implicated in itching of skin, but not vitamins. Change in personal care products can also cause itching of the skin.
Confirmation can be achieved only after physical examination, history and blood work by a dermatologist. Hope this helps. Best.

Yes, you can be allergic to B6, I am very allergic to it and I itch badly all over when I take B6.  It is rare to have this allergy but I have it and I am also allergic to Citric Acid that is all diet drinks or just drinks in general.
