Hello Nic
Yes it ocasionally happens that a visa is refused on medical grounds but there is no way that it happens without the applicant knowing that s/he has a medical condition that might be a worry.
The Panel Doctor is a doctor first and foremost, so is the Medical Officer of the Commonwealth. If either of them suspects a problem that the visa applicant is not aware of, they raise the alarm.
A lass I know told me last year that her father in law went for his meds for his Contributory Parent visa, secure in the belief that there was nothing whatever the matter with his health, proud of the fact that it is 20 years since he last went to a doctor etc.
It turned out that he had dangerously high blood pressure. He was packed off to his own GP and to a cardiologist so that they could find out what was causing it and bring it under control. The Panel Doctor sent them away and then re-did the visa meds later, once the guy's BP was down to the right levels and stable. It caused delay but it did not cause visa refusal and obviously a visa iwould be no use to a dead patient/applicant!
If there had been any worrying signs the Panel Doctor would have done something about it, I promise you!
Try e-mailing the Health Operations Centre and asking whether your meds have been cleared. They are usually pretty good about answering:
