Noted your history about type 1 diabetes, Crohn's and bulges on abdominal wall as described by you with burning and sitting too much bothering much.
As per the details you have provided this seems to be due to the following reasons:
Your weight lifting caused micro-hemorrhages and swelling of the rectus abdominis muscles. Since they are covered by a tough fascia the bulge thus caused causes, pain, discomfort and so on.
CT scan of the abdominal wall may not show this unless the Radiologist
knows what to see for. Review of the films of CT scan along with ultrasonography
and color doppler can show the reasons:
I would advise you the following in such a situation:
Stop the abdominal wall exercises.
Take an anti-inflammatory like Serratiopeptidase
This should help and a second opinion
of a General Surgeon
should help you.
Hope I have answered your query. Let me know if I can assist you further.
