I am curretnly suffering from a skin condition called pityriasis rosea. I had a fever about 2 weeks before then one morning i noticed faint rash about 4 spots on my belly went to see the nurse she said pityriasis rosea take anti histamene and moisturise. So i did a week later it got worse im mean its on my face,neck,back ,arms,legs & hands. so i went back to my surgery and saw a doctor who said the same thing its pityriasis rosea told me to keep taking anti histamene and moisturise and she also gave me a shampoo called selsun blue which i have been bathing in and smothering my body in before rinsing it off, but my goodness does it sting i find to sit and let the cream dry naturally helps reduce stinging i havent tried anything else yet its been nearly 2 weeks im getting really depressed with this now as i recently recoverd from knee surgery now i have this! would be extremley grateful to hear about others experince with this and what help you XOXOX
Pityriasis rosea should not burn unless you are scratching it. Stop scratching it and it shouldn't burn but the rash is not known to burn or itch. It's possible that it itches mine rarely does, but talk to your doctor about the burning sensation, cause it's very uncommon for it to burn like the way you are describing it.
Thank you
You're welcome and good luck. Mines at the peak so it looks like I'm gonna die. Lol don't be scared if it gets too out of control. Good luck to you, my friend.
