Technically a hernia is defined as a weakness in the muscle wall most frequently in the abdomen or groin.
All of us now have a defect in our abdominal wall...A surgical defect...It's called our ostomy. Soon or late most ostimates develop hernias it's almost inevitable because the surgical site has already made the weakness that allows gut to push through.
The only time they hurt is typically when that muscle contracts and pinches off the gut that has fallen through where it isn't supposed to be.
If the muscle pinches it off long enough the bowel can die from lack of oxygen caused by compromised circulation.
This term is sometimes referred to as a strangulated hernia or in medical terms and incarcerated hernia.
All hernias can progress and may get worse in time It is almost inevitable. However muscle strength in the area will help significantly.
Unfortunately I have the one two punch of having lost a kidney due to kidney infection that may possibly have started from adhesions when I had UC. I now have the joy of dialysis 3 days a week. One of the things nobody ever told me was that the electrolyte imbalance caused by dialysis creates terrible muscle cramps. When a cramp occurs in a place that pinches off some gut at the hernia it can be extremely painful.
But no pain lasts forever. I learned how to deal with pain when my guts shredded and fell apart leading to my ileostomy they put me on patient controlled anesthesia with a drug called Dilaudid unfortunately my body was unable to break down and use Dilaudid. For the 3 months at the hospital where I was being treated, Drs believed it was a miracle drug and thought it would prevent people from becoming addicted to morphine. My body cannot process synthetic pain medications so I had severe peritonitis for 3 months and NO-PAIN-RELIEF. I couldn't even turn side to side and was constantly being scolded by my colleagues because they figured I would develop a bedsore (these days known as a pressure injury). But I just could not turn on my side, my abdomen hurt so much I could not turn sideways for 5 minutes much less lay on my side for 2 hours. Fortunately for me my good care and work ethic had earned me some points in a way and the hospital provided a specialty bed for me that prevented me from getting a sore on my behind. Took me 5 years to win off the pain meds and rehab myself back to work but I did twice. Now retired I plan to keep on living as long as God decides that I serve some purpose. None of us gets out of this world alive. Every new life involves pain. And all of us have been given a new life.
