The severity of the symptoms, which may include muscle pains, vomiting and confusion, depends on the extent of muscle damage and whether kidney failure develops. The muscle damage may be caused by physical factors, medications, drug abuse, and infections.
Also known as a subconjunctival hemorrhage, a broken blood vessel on the front of the eye is typically a harmless condition (although see below) that clears up within one to three weeks. Subconjunctival is the term used to describe the space located just beneath the conjunctiva (the clear surface of your eye).
Ruptured blood vessels can be very painful. Blood vessels can also break due to the effects of injury or trauma. Broken blood vessels may occur without a person having any recollection of trauma. This is often the case for people who bruise easily, for example, in aged people.
