Acetaminophen (Tylenol and others) and ibuprofen (Advil, Motrin) can be used to treat a fever. Aspirin should not be used in children or adolescents to control fever. The prognosis for a fever depends on the cause. Most cases of fever are self-limited and resolve with treatment of symptoms.
Varicose veins look like swollen blue or dark purple veins, usually appearing on the legs and feet. For most people, they are only a cosmetic problem. If a varicose vein bursts, it can result in painful bruising and swelling.
Little valves are there to prevent back flow caused by gravity, and when these valves fail, that is what causes varicose veins. The blood backs up a bit, enlarges the vein and the bulges in the vein are where the valve tissue is. Source(s): masters in human physiology, retired AP bio and physiology teacher.
