Heart attack:

Heart attack occurs when an artery that’s supplying blood to the heart becomes blocked and this blockage happens due to a build-up of fat deposits in the arteries.

Sciatica is a painful medical condition that almost always only affects one side of the body especially left one. But , it can affect both sides of the body no doubt which  is called bilateral sciatica, which is rare.

This condition is named after the sciatic nerve, which extends from the spine to the legs and then to the feet.

Sometimes, gas might accumulate in the digestive tract due to swallowing of excess air while eating or drinking. It may also accumulate due to the breakdown of undigested foods by bacteria which are present in the intestine.
