A medical negligence claim usually requires evidence that a healthcare professional breached an appropriate standard of care and that this caused injury or loss. Start by speaking to a solicitor experienced in medical negligence, ideally one regulated by the Solicitors Regulation Authority, who can review your circumstances and obtain independent medical evidence. Keep appointment details, records, prescriptions, photographs, correspondence and notes about how the injury has affected you. Claims are generally subject to a three-year time limit from the treatment or from when you reasonably became aware of the problem, although exceptions can apply, so seek advice promptly.
