I Had Surgery A Little Over A Month Ago To

I had surgery a little over a month ago to repair my hiatal hernia and a ventral hernia. My recovery has been going well for the most part. The last few days I've been experiencing anywhere from extreme pain to discomfort. When I press on my abdomen above my naval, it is very hard. Most of the time it feels like gas that has no intention of escaping my body, but it's more severe than I've ever experienced before. I keep waffling about whether I should call the doctor or not.
