Possibilities include but not limited to occipital neuralgia. I suggest you take a proper consult for better evaluation.

Any sharp shooting pain may be a Neuralgic Pain. As my colleague rightly said the possibilities might also include any joint inflammation that might be trapping the nerve and any severe muscle spasm creating a Neuralgic pain mimic. Understanding the triggers of pain might unravel the true character of pain. Look for any neck muscle spasm and increase in pain with neck movements. That might help you understand the nature of pain.
