Have Small Tanish Brown Patches Under Skin, Sometimes Itchy. What Is It And How To Cure Them?

I have small patches of tanish brown very small dots the size of pin heads under my skin. They itch sometimes more than others, give or take. And I have 3 spots on my right hand and one on my left but there is a patch on one of my fingers on the left hand as well. I had this for about a month. I noticed it while I was outside back in July. I live in Alabama if that helps any. Also it started in one little patch on my right hand and now it s spread like I said up above. But they are all pretty small. None of the patches of dots are over the size of a dime. Also I noticed that day, my boyfriend and I were taking some pictures to put on our facebooks well we had to go in early because I was eating a lot of misquote bites I had about 8 on each leg and 2 on each arm. So I m kind of worried if they gave me some kind of weird desease. Also if it helps I m 23, I don t take meds on a daily basis, I don t have any medical problems, my periods are fine and I m not preganate.... Hate when doctors always thinks its those last two for everything wrong with a female... Anyways please help!
