I have a non itchy rash all over body, mainly arms and legs a little on my back and stomach, should i seek medical attention?

Drug Eruption: Drug eruptions can mimic a wide range of dermatoses. The morphologies are myriad and include morbilliform, urticarial, papulosquamous, pustular, and bullous. Medications can also cause pruritus and dysesthesia without an obvious eruption. A drug-induced reaction should be considered in any patient who is taking medications and who suddenly develops a symmetric cutaneous eruption.
