Last Thursday underwent colonoscopy examination due to colon cancer screening.
An almost elderly nurse would puncture my drip, but she couldn't find a vein. After a few times of having been wrong, she called another almost elderly nurse. She, too, could not find a vein, but after again having stung two errors I saw a few drops of blood rolling over my hand the third time. "That's right, the nurse called triumphantly.
I was driven to the examination room where the examination would take place.
Please, never trust two elderly nurses. There is no puncture in a vein, but just somewhere under my skin!
That turned out to be later, but during the investigation I had already hit the ceiling because of the pain.
"If you do not stop, I must stop the treatment, the doctor said to me ......
A treatment of more than 45 minutes, a polyp removed, and all so terribly painful just because two elderly nurses could not puncture me.
Very worthless, and for me it was the first and also the last time I set foot in this hospital.
