Core exercise and pain

[Lse88]

I am currently waiting for a diagnostic laparoscopy (10 days to go) to see if I have endo.

Today i noticed something weird. During a hydrotherapy session for back pain I did a lot of core exercise. Like an hour of core work.

Since then my core is hurting but also I'm getting pain in my abdomen like cramps.

Anyone else had anything like this?
