Vitamin B12 injection plus traditional Chinese medicine techniques for meralgia paresthetica: a randomized controlled trial.

Background: Traditional Chinese medicine (TCM) comprehensive therapy has become the mainstream treatment method for lateral femoral cutaneous neuritis. Vitamin B12 plays an important role in neuropathic diseases. This study aimed to explore the clinical effect of vitamin B12 injection combined with TCM technology in the treatment of lateral femoral cutaneous neuritis. Methods: From January 2022 to January 2024, 126 patients with lateral femoral cutaneous neuritis were selected from our hospital and then randomly divided into a study group and control group. The control group received the methods of pulling, paravertebral positive spot cutaneous needle tapping, and cupping. The study group received vitamin B12 injections on the basis of the methods of pulling, paravertebral positive spot cutaneous needle tapping, and cupping. Results: After therapy, the pain score and the numbness score in the study group were lower relative to the control group. The total effective rate in the study group was better relative to the control group. The recurrence rate and the incidence of adverse reactions in the study group were lower relative to the control group. Conclusion: Vitamin B12 injection combined with pulling, paravertebral positive spot cutaneous needle tapping, and cupping has an effective clinical effect in the treatment of lateral femoral cutaneous neuritis.
