I got bit by a dog on my hand. it swelled a lot and bled.the doctor said to get an x-ray but advil (ibuprofen) made it feel fine. should i still get an x-ray?

Dog bite: X-rays can help identify gas formation in tissues (from some bacterial infections) and can also help identify bone infection (osteomyelitis). Also x-rays may show retained foreign bodies such as a broken off tooth fragment. Take the advice of the examining physician. Infection with a bacteria called pasturella is common and early treatment with an antibiotic "augmentin" is typically recommend.
