It's generally not recommended to massage your own spine.
While you might be able to reach some areas of your back, it's difficult to apply the right amount of pressure and reach all the areas that need attention.
Massaging your spine yourself can potentially lead to injury or worsen existing conditions.
If you're experiencing back pain or discomfort, it's best to consult a qualified healthcare professional, such as a chiropractor or physical therapist, for proper diagnosis and treatment.
