I get itchy at random moments during the day red patches come up with little white bumpy spots. any idea what this could be?

No but: Whatever is causing it, I think using moisturizer on your skin immediately after bathing regularly especially in the winter months may be helpful. Try it for a week or so but you may need to see a dermatologist if the problem persists. It is difficult enough to diagnose a skin condition with direct examination, nearly impossible without looking at them.
