Dear Start, Thanks for posting your query.
There is no sexually transmitted disease
which can manifest it self the very next one day of period of intercourse as feeling itchy face, head arms, hands, tummy, back and legs. So, what could be the reason- simple stress
. you are still worried about that one day stand which is thing of past now. Kindly reassure yourself, internet is full of good and bad posts by so many people. Kindly do not pay attention. Meet a dermatologist
if still you feel the itching all over the body.
Have wonderful life ahead.
Dr Sanjay K Kanodia
