What is bothering me most?
Is the doctor clear about what is bothering me most?
Will the treatment not just treat the disease, but deal with what is bothering me most?
Am I well informed about the probability of benefit and the probability of harm?
Having decided on this, you need to consider:
Am I really sure I want this treatment - and will I blame myself if it does go wrong?
What have other people like me decided? (Look at two very good websites: patientslikeme.com and healthtalkonline.co.uk)
How urgently is the treatment needed?
Where should I have it done?
