Oro, do you know whether the statistics which form the basis for risks being described as 'negligible' are constantly updated with data from patients who have complained of side effects or after effects? I'm inclined to think not, given my own experience with the lumbar puncture in which the doctors assumed that my getting severely ill hours after the procedure was a coincidence, and dismissed my concerns, even though 'severe lumbar puncture syndrome' is documented and exactly matched my symptoms. The experience of Orange's friend seems to point to something similar - the doctors don't seem particularly interested in gathering evidence as time goes on.

I fear that the decision to recommend these procedures may be based on very limited trials, rather than from wider evidence gathered from larger numbers of patients.
