You have some degenerative disc changes in your lower neck. It is quite uncommon but these can occasionally cause headaches. More common causes of headaches (although not the cause of a majority of headaches) is upper cervical degenerative facet disease. Your radiologist did not report on this and it can commonly be missed but without evidence of degenerative facet disease in your upper cervical facets (C2-5), you cant hang your hat on this.
Your “tingling in the hands and feet” could possibly be from the “moderate canal stenosis and ventral cord flattening” but still unlikely. A thorough physical examination can rule that out.
