“Why does my child get skin rashes and muscle soreness often?”

Very interesting question and a very difficult question to give you a precise answer. In Rheumatology, there are a number of conditions that can be associated with a rash and muscle symptoms, particularly muscle weakness. One would be dermatomyositis, which is a condition causes a very characteristic rash pattern, and also causes rather significant Muscle weakness. Lupus is also a condition they can muscular skeletal pain with or without weakness and with or without swelling in association with variety rashes. Auto immune rashes are sun, sensitive, meaning sun exposure tends to worsen or cause rashes to flare. In regard to the muscle symptoms, the real important question clinically is whether there is any muscle weakness. I would trust that your family physician, and or pediatrician would be able to evaluate that and determine whether there was anything suspected that would require a pediatric rheumatologist. I hope that helps and I hope you have a nice day.
