<s>[INST] I have had pain in the back of my head on the right side for about a year now. I have had MRI of brain and c-spine with and with out contrast, and all results were normal. I have also had blood work and a lumbar puncture with normal results. I have seen several DRs including 2 neurologists and a neuro-surgean. All have said that it is muscle or nerve damage, but it still has not improved. OTC pain releviers help but the pain always returns. Is there something that they are missing? [/INST] Hello, Since the tests you mentioned resulted normal, I think that occipital neuralgia is a condition to consider. An injection in the trajectory of the occipital nerve may confirm or exclude the diagnosis and may relieve the symptoms. Hope I have answered your query. Let me know if I can assist you further. Take care Regards, Dr Erion Spaho, Neurologist, Surgical </s>
