Take any medical records, appointment letters, hospital or GP correspondence, prescriptions, photographs and notes about what happened. A clear timeline, including dates, symptoms, treatment and how the problem has affected you, can also be useful, along with details of financial losses or care needs. Bring identification and any documents about previous complaints or contact with insurers, if relevant. Do not worry if you cannot gather everything before the meeting; a solicitor regulated by the SRA can explain what further evidence may be needed and whether they can investigate your concerns.
