. it actually feels like when you have a sunburn but under your skin I have this itch on my left shoulder blade, but there is nothing there. I have had this for over a month. I went to the dermatologist he said it might be an allergic reaction to the fiber choice I was taken and I was given Triamcinolone Acetonide Cream all that did was burn. I stop taking the fiber choice still the same if not worse it feels like a burning feeling inside my skin.
