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).
The redness in the eye from broken blood vessels usually goes away naturally after a week or two. Artificial tears can soothe the eyes but will not repair any broken blood vessels. Rubbing the eye can increase the risk of excess bleeding right after onset, so avoid rubbing your eyes for as long as possible. It is rare that health complications arise due to broken blood vessels in the eyes.
