What should I do about my hiatal hernia?

I had a hernia just above my navel that was repaired when I had my appendectomy a year and a half ago. Back in December, I was lifting a box and thought I popped it out again. A week ago, I had bronchitis and was coughing- a lot. Now, my hernia seems to have reappeared, it is sensitive to touch and visible above my navel like it was before surgery. I would like to have it repaired again. Is this a good option and how can it be repaired so this stops happening? It hurts and it sticks out.
