While traveling abroad, my girlfriend and I both found several small
red bumps on the top of our hands. Hers went away quickly, while mine slowly spread. Doctors there gave me cortisone injections, allergy medication, and steroid cream to treat the bumps. Four days later they had spread on my right hand and I also had some bumps or red marks on my face, ears, and chest. We were staying in hotels together, and at a friend's place in this time.
