Marks On Thigh, Appeared Suddenly, Not Changed. Worried

Thanks for writing in to Heathcare Magic!
Very strange really!
The ash grey marks are really intriguing.
The first thing I would say, they are due to some chemical exposure.
Not necessarily applied on the skin but something may fall on cloths or may be in cloth itself and stain you when you use it and may go un-noticed as well.
If a chemical or drug exposure is the cause they will disappear in coming 15days time.
Another possibility is that they are birth marks and have been there forever, may be they were caumuflaged till now and you had some outdoor sun exposure and tanning recently and they have become noticeable.
If you have some record of earlier photographs you can make a search for them there.
If both my propositions do not work then you may visit a dermatologist for an opinion.
In any case please put a follow up.
If you have any further query please let me know I would try to answer it for you.
Wish you a great health!
