I am doing this for my son that is in Marine boot camp and stressing out about a pimply rash on his leg. He is not very informative, so I am not sure exactly if it is upper or lower. He says it is not painful and not giving him any trouble, but his drill instructors are noticing it, so it worries him. He has no allergies that I am aware of, and has always been the picture of health. No ear, throat infections. No hospital stays. Really nothing worse than a cold/flu. He did go from a northern Minnesota climate to San Diego, and of course they train outdoors, but he did not mention any itching either.
