I have a rash since I woke up it is located on my both hands, wrists, hips and back, and thighs. They are small pink raised areas and they feel as though they are like splinters stuck under my skin. No color changes with my tongue, and I do not have a fever, what could this be? I have no new medicines or other exposure but I am a healthcare worker, so I have been working in a hospital and am concerned. The only medicine I took was my heart medicine, 2 aspirin and a sudafed. None of these are new medicines to me.
