Hello. Saturday, and I was doing crunches on the decline bench, and I felt a painful burning sensation in a line across my lower a**omen. It was on the first crunch so it wasn't because I was tired or anything. Today I was doing decline flies and when I was laying back on the bench I had a painful buring sensation in my lower left a**omen. I dont feel a lump or anything but it has a burning feeling in that one spot constantly now. Is a hernia or just a strained muscle? Thanks.
