This pilot study of 10-18 year olds diagnosed with neuropathic pain will involve completion of questionnaires by the child and parent, and sensory testing in the child, after their clinic appointment. For some families, there will be an additional visit for MRI. Children will be recruited from the Chronic Pain Outpatients service at Great Ormond Street Hospital NHS Trust. This research is funded by Great Ormond Street Hospital Children's Charity.
