I feel your pain! Nothing is more uncomfortable than feeling your intestines slipping down into your testicles!
This should cheer you up:
When I was a teen, I developed a bilateral inguinal hernia (both sides) from my job as a bricklayer's assistant.
I elected to try and repair it with sit-ups on an incline board and weights behind my neck.
Everybody told me I was crazy--but--I did not want surgery.
After 6 mos. of daily situps (three times a day!) I had managed somehow or other to strengthen my lower abdomen enough I no longer had the detectable slippage!
Here is the ironic part. My doctor had diagnosed me as needing surgery about the time I was fighting with the Draft Board and the Selective Service. By the time the Army doctor examined me, I no longer had detectable hernias!
If I had NOT done all those exercises, I probably would have failed my Armed Forces medical exam and wouldn't have had to go to prison! But I passed the exam, and the rest is--unfortunately--history!
To this day, I've not experienced any problems again. I do continue to do situps. . . just in case!
