Thanks so much for the advice Abhijeet!! :)
Dear Melissa,
Please don't think of aneurysm at all. It will drive you crazy.
We all get some unusual pain while doing stretching exercises.
So please don't worry.
If there is some pain, just don't do the stretches.
It's as simple as that.
And also, while in bowel, please don't strain yourself.
Else you can have some laxatives before going for the same.
It will go, once you stop straining.
Relax.
Feel free to discuss more.
Regards...
