Is it not allowed to seek a second opinion?

I have done urine analysis and it returned a candida negative result but the homeopath is still suspecting that I have it. I have been avoiding milk for the last six weeks and now bread, etc. has also been added to the list.

I need to know if I am being diagnosed correctly or should I religiously believe in what my homeopath says. I am asking this as I do not know of any other classical homeopath in the country where I live.

Regards,
