Almost all hernias require surgery, preferably before complications occur, to reposition the herniated loop of intestine and secure the weakened muscles in the abdomen.
Is good to know that some clinical studies have reviled that open hernia repair has less early post surgery complications, serious complications and smaller recurrence rate, than laparascopic one.
Surgeons in this field have recognized that patients who postpone surgery for an inguinal hernia only occasionally develop serious complications, such as strangulation.
If the symptoms you have get worse with time and you find relief from pain only when lying, you should seriously think about getting hernia repair.
Talk about this with your surgeon!
