Scarlet fever? Scabies? Pityriasis? - picture of scabies

He had a sore throat in February. Toward the end of my round of antibiotics, he developed a rash on my arms. It burns, but dry, scaly and red and ugly. It spread to his legs and torso. I thought of scarlet fever, and how can I find annoying, I ignored. One of the ladies at work said it sounded like "what you get after a throat infection. Finally, in June, I told myself, 'Wow, I had this rash for a very long time" and again) in the (same doctor. He said that the fever was not red, it was pityriasis rosea, and prescribed an oral steroid. The problem is that I have taken steroids and had no objections. I also read on pityriasis it is very rare for this period (7 months). So, I'm sitting here, to understand what could be hell. The attempt to see a diagnosis of pictures on the Internet is almost impossible, I saw seems to have any outbreak. I lik images of scarlet fever, scabies, pink, secondary syphilis, which are alwaysand I did.

So please, can someone tell me how they differ from each other? The rash on my arms, legs and belly and a little on the hands and feet. Not good in my back, face, neck, palms or soles. Besides the attractive, not really bother me, no itching or pain. He came at the end of my round of antibiotics for sore throat. If it makes a difference, I had a further severe sore throat for about a week later, but with analgesics and salt water are allowed and treated.

Should I go to the doctor for an exam or follow his advice to "wait it out?
