About a week and a half ago I had what I thought was a large bug bite on my upper left chest. I couldn't help but scratch it and it became inflamed then flaky with a ring around it a couple of days later. I thought I had ringworm. Around the same time the first bite began to flake, I developed a tiny pink bump between my breasts that itched. I thought it was another bug bite. This was about a week ago. This tiny bump started getting other tiny bumps nearby. A few days later these bumps started multiplying, spreading, and getting red (possibly from all the scratching - I can't help it). I also developed clusters on the left side of my back, fewer clusters in my upper right arm, and recently the right side of my neck.
I finally saw a dermatologist today and he thinks it's Pityriasis Rosea. He asked me a lot of questions about my medical history, etc. and I was so focused on the incredibly itch on these parts I forgot to mention that I recently had a small rash under both my eyes that lasted about 3 weeks. It was also dry, sightly red and flaky. This was immediately before the first Herald patch developed.
Immediately prior to my eye rash I had 2 canker sores in my mouth that lasted a month. I also had ongoing stress headaches that lasted about a month around the same time my mouth sores were healing and eye rash was developing. I assumed it was because I had a lot of stress in my life, wasn't exercising, eating well, sleeping, etc.
Does anyone know if these symptoms are related or if there's a possible underlying cause I should consider? I'm wondering if I should schedule another appointment so I can talk to my dermatologist about this. Any thoughts?
