Hello doctor I am a 20 years old female. Actually I have been noticing these light patches or rash whatever they are of red or light red color sort of on my thighs and they are painless and non itchy. When I touch that area, I feel nothing but these spots or rash sort of things is seen from the outside. Also, few weeks back I have been told I am vitamin d deficient and calcium deficient too. Also, I have been suffering from a skin problem earlier know as eczema but that was only in my right hand side little area. Only that area is having eczema which is now seasonal because it happens whenever season changes and go away on its own too at times. The main thing is these are red light red or light purplish sort of (color not so sure because they are very very light) patches or rash or whatever on the upper thighs. It's been more than two months I have been noticing them. Although it didn't bother me because these are painless and non itchy. Though at times when I wear some sort of jeans and all, I can feel little itchiness but that's because of the cloth maybe? Though earlier it never happened. Also, I have gained little weight too. I am telling all this because anything may be the reason to this problem. But please help me out with this.
