whenever a person hits an extremity hard enough to break the skin we become concerned about a possible fracture. your friend probably would be well-advised to head for an urgent care facility for an x-ray especially given the level of bruising you describe. meanwhile your roommate can elevate her foot apply a compression bandage (like an ace wrap) for moderate compression (don't wrap it too tightly! ) and apply ice packs to the foot. these steps -- the so-called rice approach for rest ice compress elevate -- may help reduce swelling which hinders the body's healing response. i hope your roommate feels better soon!
what do i do if my college roomates foot is turning completely blue after tripping and hitting it on the table earlier? . the top of her foot slammed into the sharp edge of it breaking the skin. but not bleeding. it's hurting her slightly to walk on it.
