The spotted bruise on feet and legs is likely to be type of purpura
It may be progressive pigmented purpuric dermatosis
.. Also known as Schamberg's disease.
It is benigne condition, there is mild inflammation of capillaries in the skin...so, it is a short of capillaritis.
It may go away by itself in some cases...
Or it may remain for few years.. Gradually progresses.
Oral vitamin C
and K might be improving the disease.
Application of thrombophob would be helpful.
You do not worry, as the disease is not serious one.
Still, you consult dermatologist
I hope you got my answer.
