Muscle spasms in back neck (right side) followed by pain that radiates up into head. It began as spasms that locked up the right and front side of my neck. Following the spasms and pain, it feels like something is in my head where the pain was. The symptoms are getting worse and lasting longer. A brief history.....I was diagnosed with Multiple Myeloma in November 2014. Had a SCT in July 2015 which went very well. In December 2015 I was declared to be in remission, and am on an every other week Velcade regimen, and Zometa every two or three weeks. I am 70 years old and in generally good health. Thanks. Marti
