"Examination of my ankle/foot"

I agreed to a student to be present at the examination who was nervous and lacking confidence. The Professor did nothing to help the student with this, and the Professor's manner was very self important. The Professor showed irritation with my struggle to rate the pain in my foot. I am in daily pain when working as a dog walker, yet all medical examinations have found nothing wrong in my foot. I was told that it is a mechanical problem and that I could benefit from specially fitted shoes, but I feel that it is unlikely to be anything to do with my shoes. The Professor's treatment of me and the student irritated me and caused me not to ask questions. I left the consultancy with no idea of what "mechanical " meant in relation to my ankle problem and how to treat it. Medical professionals in the N.H.S are supposed to serve the injured tax payers with their expertise. Not to show off in front of patients and nervous students. I have no medical knowledge, but the fact is, there's something wrong in my foot and the professor doesn't know what it is.
