20-week follow-up period;\n* Visit frequency: 2 remote visits by phone/video call (1 week and 12 weeks after the injection); 2 on-site visits (6 weeks and 20 weeks after the injection).'},

least probable level of certainty according to the NeuPSIG/IASP (Neuropathic Pain Special Interest Group / International Association on the Study of Pain) grading system.\n* A score of at least 4 out of 10 points on the Neuropathic Pain 4 Questions (DN4) questionnaire.\n\nExclusion Criteria:\n\n* Complex Regional Pain Syndrome Type 1 and Type 2.\n* Any other painful condition or disease that requires treatment (only mild to moderate episodic migraine treated with triptans and/or non-steroidal anti- inflammatory drugs (NSAIDs), if any, is acceptable).\n* Postsurgical/post-traumatic
