Write a service page

I work in marketing at a private health clinic. Help me write a web page for one of our services.

Context: People compare several clinics in one sitting, often late at night. They look for who will treat them, what the treatment involves, how long recovery takes and what the whole thing costs.

Before you start, ask me for anything missing from this list:
- The service and who it is for
- What happens, step by step
- How we charge
- What we cannot promise

Then:
1. Open with who this is for and the problem it solves.
2. Explain what happens in order, in plain words.
3. Explain cost or how pricing works.
4. Answer the five questions people ask before getting in touch.

Give me:
- A headline and a one-line summary
- The page, 400 to 600 words, with question headings
- One call to action

Rules:
- Use only the facts I give you. Where something is missing, write [detail needed]. Never invent a number, a name, a quote or a source.
- Give general health information only. Never write anything that reads as advice on a person's own condition, and never suggest a treatment is certain to work or free of risk.
- Write in plain English, in our voice if I have given you a sample.
- Do not tell me what the rules or regulations say. If something may be restricted, flag it and I will check.

Finish with a list headed "Check before this goes out". Include these, plus anything else our clinical lead or the registered manager who approves marketing should see:
- Claims that the treatment works or is safe, and the evidence for each
- Any prescription-only medicine named or hinted at on the page
- Titles such as specialist or consultant, and the registration behind them
