My left elbow was killing me, like I hit it with a hammer. Every now again it would pop and all would be ok for a whil. Went to the Dr. They sent me for x rays and to a orthopedic surgeon. They did a scan and wanted to operate. I was scheptical so they sent me to a neurologist. They wanted to open myelbow up and put the tendon on the other side of my elbow. I said no. In a day or two, I went to the chiro. What's to loose? She adjusted betweek my shoulder blades where the nerve is that feeds your arms. CRACK!!! 10 min later the pain was gone. Yep. I'm a believer. I have another story or two but you get the drift. Sciatica for 6 months? I won't tell that one.
