Can the panchakarma techniques work for back pain?

Possibly. According to ayurveda, panchakarma can be helpful for many health issues by restoring balance and clearing toxicities from the body. Back pain, in particular, is addressed as a vata disorder for which the panchakarma therapy of basti treatments is prescribed. In addition, daily massage treatments can also be helpful for back pain. If it persists, however, consider a full medical consultation.
