How can i heal hernia without surgery needed and what are the do's and dont's?

Depends: Hernias are usually repaired using mesh with surgery. If you do not want to have surgery, you should avoid lifting and strenuous activity. If it is an umbilical or inguinal hernia you should avoid intra abdominal pressure which can cause bowel to go into the hernia which is very dangerous. You can try to use abdominal binder or compression garments to prevent increased herniation.
