The first time I had a mammogram following a crop of breast lumps, I was warned that it would be mildly uncomfortable. Consequently, when it turned out to be excruciating, I assumed that something had gone wrong and promptly passed out (with one boob still trapped). I came round on the floor and the radiographer kindly lowered the machine so that they could 'do' me while seated in a chair. Then I had to wait for an hour in the waiting room until a doctor came to check me out and ascertain why I had fainted before letting me out to drive back to work. Although he was a man, he thankfully took my word for it that I had gone into shock with the sudden, unexpected agony.
Had umpteen mammograms since which have been OK but not exactly what I would choose for a wee treat.
