need not to worry.
multiple bruises may be due to various reasons.
platelet disorder may give rise to this picture.
rash in legs may be due to thyroid disorder
it may be due dermatitis
,eczema or it may be urticaria if it is short lasting.
abnormal pap smear
bears no relation with rash i think.
you should consult a dermatologist
he will be able to comment about its relation with thyroid and pap smear after examining the lesion..
it may take investigations to reach a diagonosis.
you will also have biopsy and thyroid medications.
these may be costly.
try to arrange it.
best of luck.
