U need not to see any specialist.Might be u r suffering with senile purpura
. Though these type of lesion seen after 65 yr of age but few patient develop it after menopause
. AVOID TRAUMA ON ANY PART OF BODY.Just notice that ur daily routine activity or exercise etc affect it. Start vit C tablet daily for long time. Also,add estrogen
rich diet in ur daily routine.Still u have doubt than consulit onco-haematologist for the same.
