Having to cough after a median sternotomy. Not only very painful, but scary! I was amazed how long it hurt just to be driven in a car as well (wasn't allowed to drive myself for 6 months).
Median sternotomy is when the breastbone is cut open. Often this is done for open heart surgery, but I had it so as to remove a retrosternal goitre (when some thyroid tissues decides to wander down into the chest and grows there, for decades in my case to reach the size of a melon - yuk!).
I was in an ATV accident, and my pancreas split open. I had a few internal organs removed because of it, an my diaphragm was torn, so they repressed my ability to throw up in the hospital, and I was so nauseous from the pain! THAT was the worst!
Surgery has got to be the worst my Dr even informs other Dr's if surgery is required that I don't like pain and they go all out to help keep my heart rate down since it can go out of sync cool. Anyways, worst pain was my ceasarean and post-op difficulties, could barely walk for the 1st 2 wks.
Yikes last year when they took bone from my hip to use it in a spine fusion. Ouch. But a broken rib is right up there. Any bone injury really is awful. That and endometriosis. But the bone graft makes you fall to your knees. As does any spine surgery. And an unstable vertebrae that moves. Thank God it was fixed.
I heard this statement the other day - "food poisoning is more painful than child birth". I, myself, thought I was going to die for 3 days after some bad seafood, however, I cannot relate to the pain...
