It was less than a disagreement. I’m sorry that I over-emphasized this point. The first time the pressure was Hgmm 26⁄18, the second time 19⁄17. The second doctor said that the pressure can fluctuate, and her equipment is not enough to settle the question. (She is an I-don’t-know-the-correct-term national health service doctor, the first one is an expensive private doctor with better equipment, and more time for a patient.)

My recommendation for more independent opinions (or, actually, more measurements) stands.
