In case of an inguinal hernia, if it is less than three days old, you can still reabsorb it by gently massaging it back after reducing the internal pressure in the intestine.
If the hernia has been there for longer than a week, chances are that the body has already taken care of it by separating the intestine from its hernia. Eventually, with time, the two will separate completely.
In any case, it is important to take care of the main reason why the hernia happened, which is due to too much internal pressure pushing into the inguinal areas. Chi Nei Tsang is recommended with deep work into the sacral cavity.
