I have been waking up with rashes on my back and arms and upper legs as well as under my breast. They are itchy for a short period of time. I feel like something is crawling on my body all the time, but there is nothing there. My side is now all red. It looks different on different parts of my body. On my back it looks like hives. On my arm its kinda scabby . Under my breast its very red like and blotchy like. My leg it looks like a mosiqtoe bit. Please can you tell me what it might be. Thank you , Ann
