Keep in mind that there are many forms of regenerative therapy that are not specifically stem cell as regulated by the FDA.

Neck and Back pain by themselves are bad enough, but what if the pain is accompanied by numbness or weakness that radiates from the neck or back and out toward the arms, or down to the buttocks, thighs, and legs? These additional and discomforting sensations can be categorized as coming from nerve root irritation (also called sciatic pain when in the leg). They are frequently a result of degenerative disc disease, but other causes exist including nerve root irritation without degenerative changes, mechanical problems, and ligamentous strain involving structures in or near the spine.
