Did you undergo an open incisional hernia
repair or a laparoscopic one?
If you had a laparoscopic repair, then the tacks used to fix the mesh can sometimes lead to the symptoms you are complaining of. In open repair, extensive dissection is done and that can lead to this feeling as well. These complaints will settle down with time. If you are overweight
, then try to reduce a couple of kg's and you will feel better.
You have already been assured by getting a CT done that it is not a recurrence. Another possibility could be gastritis or an peptic ulcer
. You can try a proton pump
, etc) for your pain and see if it helps you out. If the pain still persists, then you should consult your doctor.
Hope you get well soon
