I bumped my arm, close to my wrist today and it seems worse than a bruise.  Very dark purple and raised.  Should I be concerned?

Yes: You are of an age where fractures become more likely with relatively minor injuries. If this was a fall on outstretched hands or even a bad bump, it could well be a fracture. You should put an ice bag or frozen peas on it, tape your arm gently on a flat piece of wood, or even a solid spatula, keep it above your heart, and go get it x-rayed. Take off all your rings first. Good luck to you gal ...Read more

Hematoma: What your are describing sounds like a hematoma which is escaped blood from the vein which has accumulated in the tissue around the vein. This is why the skin is bruised (black and blue). The pain is from the irritation from the multiple needle sticks. Apply ice for the first 48 hours then heat. Ibuprofen will also help. This should resolve over about one week. ...Read more
