Hello Dear User, Thanks for using our service. As I always say, Physical evaluation is needed in order to give an exact diagnosis. However given those symptoms, here is a conclusion about them. It can be: 1. Secondary Syphilis: is a sexual transmission disease, caused by Treponema Pallidum, characterized by fever, rash Cutaneous multiform , iritis, alopecia, and severe pain in the head and joints. I encourage you to evaluate yourself looking for lymphatic nodes affected, near genital area, and be attentive to any other symptoms. I strongly recommend you, to do a VDRL test and FTA test, in order to confirm this. 2. Contact Dermatitis: Some irritant substances, can produce this type of lesions, however, it is a non common patron, because of distribution. Unless you had contact with an irritant substance in all your body. In any case, this conclusions must be confirmed with studies and you should visit your specialist (dermatology or Clinician), to have a physical evaluation, with adequate anamnesis (interrogation), and for evaluation on laboratory tests. I hope to be giving you helpful information. Regards Dr. Nieves Romero.
