Marks on skin changing..not sure if dangerous?

About a year ago I noticed I had 3 circular marks going up my neck that were NOT there before. They looked slightly grey, almost like a watermark, and feel rougher than the rest of my skin. Recently they seem to be becoming bigger and darker. I have no idea what they...?!

I'm 21, female and British Indian - if this helps at all.

Sorry if the photos aren't very clear!

Hello,
One possibility for your rash is of 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. Topical and oral steroids are needed. Water, sweat, and soap may cause irritation and should be avoided in the disease. Topical zinc oxide and calamine lotion are useful for pruritus.

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.
