Thank you for all the information,
Hernia usually causes a swelling.
It increases in size on coughing, straining.
It may disappear during sleep.
You can also push it inside abdomen gently when you are lying down.
The treatment of hernia is surgical.
Often treatment depends on symptoms & discomfort you are feeling.
In small hernias with no symptoms, sometimes wait & watch approach is taken.
In planned surgery, the risk is less.
Sometimes hernia can get obstructed & strangulated.
In that cases it will need emergency operation & there can be complications.
You can have an evaluation by a surgeon.
I hope this information helps.
