My son who had cervical fusion c-3-4-5 or 4-5-6 about five years ago is now experiencing extreme (no feeling at all) in the toes and the end half of each foot. He is 58 now but when he was 6 he broke his femor up near the top. He fell off of a bicycle. We lived in a small town and the Ortho. Apparently wasn t very good because I obtained the X-Ray and he had not set it properly. My son has had to wear a lift in one shoe to protect his back ever since he joined the Marines and nearly wasn t accepted because of thisbecause the medical exam detected this. The simple addition of a lift(?) corrected this. I don t believe degenerative disc disease can be passed down but I have had my lumbar (L-4-5&S-1) fused (1988) and my neck (C-4-5-6-7) fused in 2003. My daughter also experiences neck and low back pain. This is a lot of background but I thought it might help. My sons numbness in his feet should be seen by a doctor but you can t tell a grown man what to do even if you are his mother. I suspect his health insurance may be the reason, he changed positions recently. He is a computer graphic design artist and I m pretty certain that his job is hard on his neck. Can his neck problems and the numbness in his feet be connected. Please advise me. DJKJ
