Hi, i have a round rash like marks on my arms and my chest. i have also experienced fatigue, muscle pain and joint pain yesterday?

Circular rash: Round rash areas can indicate one of several problems. It can be a type of urticaria (nummular eczema or erythema multiforma ) which is an allergic reaction, or it can be an infection (ringworm or Lyme disease), or it can be a series of insect/parasite bites with allergic reaction surrounding them. See your Dr for diagnosis and treatment ASAP since you are experiencing fatigue, muscle/joint pain

Needeval to know.: If the rash and the joint/muscle pain & fatigue are all related to one condition, then this would require an actual evaluation to determine the cause.
