Hello. Welcome to ask the doctor.
I understand your concern.
I have seen the attached photograph also.
As per details, the most likely possibility for your symptoms is a condition of skin called Vasculitis.
It may be caused by recent infection, any drugs like pain killers , oral contraceptives, Doxycycline, isotretinoin etc.
I will advise you to get your Hemogram with ESR, ANA levels , Liver function tests and kidney function test done.
Visit your doctor so that he can order tests for you.
You can share my opinion with him.
I hope it helps.
