A not is on my sphincter muscle it is as big as a grape do i need to go to the er it just happen an hour ago

Probably not: A sudden grape like mass on the anal sphincter is most likely a hemorrhoid. Unless you are in severe pain, er visit is not necessary. Have your primary care provider evaluate this soon.

Let me help: Straining can push an internal hemorrhoid through the anal opening. This is known as a protruding or prolapsed hemorrhoid and can cause pain and irritation, if is not very painful you go to your doctor. Or could be external hemorrhoid.
