A surgical error claim may be possible if a healthcare professional fell below a reasonable standard and this caused avoidable injury or loss; an unwanted outcome is not automatically negligence. In many cases, the usual time limit is three years from the treatment or the date you first reasonably became aware of the injury and its possible cause, although exceptions can apply. Medical records, operative notes and an independent medical expert’s opinion are often important. Consider speaking promptly to a solicitor regulated by the SRA who handles medical negligence claims, as they can assess the evidence and limitation period.
