I have 3 mm of anterolithesis of c3 on c4 and 3mm of retrolithesis of c4 on c5. What degree of degeneration do I have? I have had tingling and numbness and recently severe pain in my right arm, which is intermittent. Now I also am noticing intermittent tingling in my left hand and lower arm. In 1995 I had cervical diskectomy for herniation of c5 c6 left and c6 c7 right with excellent results. Thank you
