Hey, I understand how frustrating it can be when dealing with a chronic pain issue with no definitive diagnosis related to the symptoms, especially in someone so young. I also take Cyclobenzaprine for muscle spasms in my neck and it is helpful. If I may...just a slight, but important, distinction about "addictive personality", which is actually a common misnomer and is, more accurately, an addictive tendency, often genetic, and not part of our personality. I wish you well in your pursuit of comfort and treatment.
