Changed Diet. Supplements Like Multivitamin, Potassium, Calcium. Developed Scar Starting From Leg To Hands. Remedy?

I am 44 years old. A couple of months ago I started exersizing and changed my diet for the better. I have lost twenty five pounds..I also started taking a new multivitamin and a few other supplements..zinc, potassium, calcium, b12, and selenium. None I take are over the recommended daily ammount. A month into taking them I developed a rash starting on my legs and spreading to my arms...Its worse at night..itchy as hell.. I'm miserable. It has been over a week. I went to the doc He is not sure what's going on. Made some guesses. I do know the multivitamin has colors in them..red yellow blue, cause they are gummies. I already had stopped taking the supplements for the last few days. I have also completely switched to whole wheat instead of white but I try not to eat bread much.

I did not tell my doctor that I just experienced a very stressful event in my life.
Any ideas??





I did not mention to the doc that I have had a major stressful event happen in my life recently.
Any ideas..
