[|AI|]  Hi, I have gone through your question and understand your concerns. In my opinion, most probable cause of your symptoms may be occipital neuralgia, a condition where occipital or upper and back neck nerves are pinched or compressed along their way. Another possibility of your symptoms may be high blood pressure. You need to discuss with your primary care Doctor above-mentioned possibilities and tests needed in order to have a correct diagnosis. Hope this answers your question. If you have additional questions or follow-up questions then please do not hesitate in writing to us. I will be happy to answer your questions.
