Calculators and tools
Work out which clinics fit what you are looking for, what treatment is likely to cost, whether you fit the profile clinics treat, and how your symptoms score today. Nothing here asks for an email and no result is stored.
Every calculator runs in your browser. Numbers you type are not sent anywhere, and results are not saved between visits.

What these are for
Researching a treatment you pay for yourself involves a lot of arithmetic that nobody does for you. What is this likely to cost once travel is in it. Am I even the sort of patient this is offered to. Is my knee bad enough to be worth it, or bad enough that the window has closed. These tools do that arithmetic and show their working.
The cost and matching tools are built on what clinics listed in this directory actually publish, so the starting figure is not a guess and you can click through to the profiles behind it. Nothing in the matching is weighted by what a clinic pays for its listing. The screening and symptom tools encode what clinics ask on their own intake forms, which is a reasonable proxy for whether a consultation is worth booking.
What they are not
None of these is a diagnosis, and none replaces an examination. A score of 62 on a symptom questionnaire is a number to take to an appointment, not a decision. The candidacy tool can tell you that active cancer rules treatment out today because every reputable clinic screens for it, but it cannot tell you that a treatment will work, because for most of the conditions clinics advertise, nobody can say that yet.
Use them to arrive at a consultation with better questions and a realistic budget. That is genuinely worth something, and it is all a calculator can honestly offer.
