Possible psoriasis

Married mother of one. 29 years old. Decent health other than some ear issues and allergy issues.
4 weeks ago started getting a red welt like spot on my left shoulder right on top of my birthmark. The skin is raised and the in the middle the skin was flaky and dry. Now in the last week I have 8 small spots like the one large one on my shoulder, but on my right arm 10 on the left arm and a bunch on the trunk part of my body and couple of them on my upper thighs and on the under side of my breasts:(. Do not have any on my face, hands, feet lower legs. I might have it behind my ear. The spots are small and red and raised a little and the skin looks a little distorted on the bigger spots if that makes sense. They do not itch, but the flaky skin is quite rough.

I seen a doctor and he tested for fungus and did some blood work. No infection and no fungus, blood work normal.Doctor did say it blanched. Whatever that means. Can't get in to see a Derm for another two months. The spots are increasing everyday. They seems to be on the covered parts of my body

The only changes in my life are that I got a kitten in late October.

The spot on my shoulder does seem to improve when I put rose-hip seed oil on it, but it never goes away completely and that is the same for the smaller spots. It helps with the flakiness, but the raised and obviously distorted skin stays.  

My G-ma had psoriasis and another autoimmune disease called celiac "sp". Not sure if this could be what I have.

They resemble what this little one has, but I do not have as many and only about 4 or 5 are as big as the bigger ones in the photo. But they do not itch at all as of right now.

The only sickness I have had is my first bout of strep throat on October and a sinus infection.
The spots seem to appear close together. Like 3 or 4 will appear within just a few cm from each other or in the same general area. I do not see any in my private areas or buttocks. They do seem to get bigger.

Derma said I have Pityriasis Rosea. I had never heard of it. He said that is why I was feeling so ill a few weeks ago with a high fever, head ache. I guess the other doctor was wrong and it was not a sinus infection. The rash is still here and looks to be getting worse. I could have this for 6 to 8 more weeks.

Hello,
If the spots have suddenly appeared then it may be due to an allergic reaction but other possibilities like viral rashes, pityriasis rosea etc also need to be ruled out. These may also present with spots on abdomen. In pityriasis rosea, initially, a primary plaque, called a herald patch, is seen. Then it is followed by a distinctive, generalized rash 1-2 weeks later. The rash lasts approximately 2-6 weeks and is found in a Christmas tree pattern over the trunk and abdomen.

It is very difficult to precisely confirm a diagnosis without examination and investigations and the answer is based on the medical information provided. For exact diagnosis, you are requested to consult your doctor. I sincerely hope that helps. Take care and please do keep me posted on how you are doing.
