Got an bone hard lump on left backside of head above the occipital bone with burning sensation there and on my neck and shoulders. Any ideas?

Superior trapezius . The unifying symptom you describe is the broad region of discomfort. This muscle runs throughout the region you describe. Perhaps is spasm in this muscle with tendonitis where it connects to the occipital skull. Your signs and symptoms are odd, and you should see an osteopath to sort this out.
