How can a strangulated hernia get reduced on its own after taking pain killers?

Hernia is a common surgical problem. Hernia can be complicated with many things. Strangulation is one such thing. A hernia gets strangulated when the contents of the abdomen comes out and twists. As a result the vessels supplying the hernial contents get crushed and the blood supply is cut off. If your hernia has got strangulated, you will feel colicky abdominal pain, with nausea, vomiting, abdominal distention and constipation. This is a surgical emergency that requires immediate attention. Unless, the contents can become gangrenous and rupture. 

If you have a strangulated hernia, the doctors will advice you to have strict bed rest and elevate the foot end of the bed. They will also prescribe you analgesics. Surprisingly, some people improve with the provision of pain killers. This occurs as a result of relaxation of the muscles surrounding the neck of the hernia. Analgesics can relax the muscles. The same thing happens when your are taken to the theater and anaesthesia. Anasthetics are also muscle relaxants. Sometimes the muscles can get too loose and the hernial contents can get back in to the abdominal cavity. This can be an disadvantage, because the surgeon might have to open into the abdominal cavity, in order to find the strangulated bowel loops and look for possible perforation.
