hi there, the bleeding along with feces could be due to either an anal fissure
or due to haemarrhoids or piles in common words. Fissures are quite painful and the itchiness could be one menifestation of it. You should visit your doctor and get diagnosed one way or other, the ingrowing hair could actullly be folliculitis
and as it is infected you will need to take a course of antibiotics to take care of it. You should never squeeze a boil or a follicle as it invariablely gets infected and heals with a scar. Take plenty of fluids and high fiber diet and avoid refined and prepackaged food to avoid constipation
and it could lead to many more complications besides the one you are facing now . Take care.
