Though there are several air beds on the market, Sleep NumberÂ® beds are the only ones to feature DualAirâ¢ technology. This allows for an individualized level of firmness on either side of the bed. Each bed comes with a modular base and a 25 year warranty. Customers also receive a 100 day in home trial, during which time the bed can be returned for a refund if they aren't satisfied. Sleep Number beds come in a variety of styles and prices, ranging from approximately $1,000 to more than $4000.
Anal fissures are caused by trauma to the anus and anal canal. The cause of the trauma usually is a bowel movement, and many people can remember the exact bowel movement during which their pain began. The fissure may be caused by a hard stool or repeated episodes of diarrhea.
During an exam, a doctor can also find out whether another condition may be causing the fissure. Having several fissures or having one or more in an area of the anus where fissures usually don't occur can be a sign of a more serious problem, such as inflammatory bowel disease or a weakened immune system.
