“Tummy tuck pain 2 years later”

I am 2 yrs post-op and have been experiencing extreme tightness in my abdomen, especially after eating a meal.

I work allot in my yards and started with this severe discomfort after I work in the yards. My clothes are terribly uncomfortable when this is happening and have to get out of even my underwear because i feel so tight. Is this normal or have I injured the abdominal muscles. I get some relief when I take a muscle relaxer.
