Few days ago started to feel some kind of itchiness on my right thigh and i found a pimple like bump.which was small red and head filled with puss when popped,blood came and itichiness stopped.now the whole area is red and warm.like there is an infection and when popped the head again a lot of blood and white coloured clotted puss came. still the area around the head is red and swollen.really painfull. now i got 3 pimples of the same kind.near the first one.but those are not painfull or red.
