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).
Best Answer: If it is bright red and looks like it's filled with blood (the white is all red) you've broken a blood vessel. It's generally not serious and will clear up in about a week. That can be caused by things like hard coughing, vomiting, etc. If it's just bloodshot, like a lot of red lines, that's an allergy or some other kind of irritation.
