How Can Rashes And Welts On The Skin Be Treated?

Hi my name is Glenda Reeder. I have been struggling with Candida and Leaky gut syndrome. My question is---Iget this crazy rash and welps on my skin everytime I touch or scratch anywhere. I will feel a spot tingle and get hot then a large welp or knot will appear. It looks like termite tunnels running across my skin. It will last for about ten minutes and then it turns red like a burn and then just goes away as fast as it appears. Also it stings like little needles sticking me . I dont break out in the places a yeast infection breaks out. Mostly my arms, legs, face and scalp. IT IS CRAZY!!!!!! Is this normal? Its as though it wants nothing touching me. I am on the leaky gut diet strongly but am still breaking out a lot.
