Not me, but a friend of mine went to the ER back when he was in his early 20s. He had been suffering stomach pains all day, and finally another friend of his suggested he may have appendicitis, and should let him drive him to the hospital to be sure.
When they got there, he and the friend were taken to a cubicle, and told to undress completely, and given a gown to put on. His friend wanted to step out, but the patient was so nervous and scared at the thought of being completely undressed. He realized they were probably going to be very thorough in examining him.
When two doctors walked through the curtain of the cubicle, he got really scared. The doctors asked the friend if he wanted to step out. The patient said he wanted him to stay with him.
So the doctors had the patient lie flat on his back, and then raised the gown to his chest. He turned white with embarrassment when he felt his lower body and abdomen being exposed to everybody in the cubicle. One of the doctors palpated his abdomen, while the other one took his temperature and blood pressure.
Finally one of the doctors said it appeared to be a possible case of appendicitis, but they had to be sure before taking him to surgery.
They called in an orderly, put him into a wheelchair, and wheeled him into a room at the end of the hallway. The friend was once again asked if he wanted to wait in the waiting area. The patient again insisted his friend stay with him.
After they got to the exam room, which had more sophisticated medical equipment, the orderly helped the patient out of the wheelchair and onto the table. It was a very heavy-looking table, equipped with all kinds of attachments.
As my friend sat up on the table, the doctors told him to lie down, and then had him scoot his rear end to the edge of the table. The one doctor slid out the stirrups on the side of the table, while the other doctor assisted my friend in putting his feet into them. My friend was doing what he was told, but he was shaking from the fear that was grippping him.
When he was in positioned into the stirrups, one of the doctors told him that usually the patient would be given a series of enemas to be sure they were clean inside, but since this was an emergency situation they would have to forego that part.
When one of the doctors walked over to a cupboard and pulled out this strange looking instrument with a long hose on the end (a flexible sigmoidoscope), it took him a few minutes to comprehend exactly what was happening.
Seeing his state of nervousness and panic, the doctors told him he would need to relax, otherwise he would be quite uncomfortable. Just trying to insert the tip of the scope was a major battle. My friend started to squirm, and trying to pull away from the scope going into him.
After the tip was finally inserted, the doctor began to advance the scope farther up his rectum. Every little movement made my friend yell out. He later told me that all he could feel was a feeling of having to crap. His other friend said that all he kept saying was: "I'm gonna go! It's coming out! Oh God, I'm poopin'." As the scope was being withdraw, the feeling was truly magnified. He kept saying "Stop, I'm shitting. I can't hold it! Stop!".
Finally, after the scope was out of him, he was truly humiliated, mostly because of his actions and words during the exam. His friend tried to comfort him, and rubbed his arm. Meanwhile, while he was still in the stirrups, one of the doctors began to massage his abdomen, partially to calm him down, and also to get him to express some of the gas that had most likely been pushed into his bowel.
As he started to massage the abdomen, rather firmly, my friend let out a huge fart. He hadn't expected it, and he was mortified that he had done that in front of a room full of people. After that, a series of farts ensued, and since he had no control whatsoever over his passing all this gas, all he could do was lie there and sob.
Later, when the friend was relating the story to me, I tried to talk to the patient about his feelings during that exam, but he simply refused to even acknowledge that it even happened. Needless to say, he now has a tremendous fear of going to the doctor, ANY doctor, never knowing what they might do to him.
