Chronic pain has a huge global prevalence of 20% and in a country like India which has been labeled by the UN as the most populous country in April 2023, the problem is likely to explode and pose a huge challenge to Indian Practitioners. An addition to this can also be due to an expected doubling of individuals over 65 years of age by rises in the aging population. Pharmacotherapy which is the mainstay for conservative medical management (CMM) often seems to be inadequate and/or has a potential for a range of side effects. The patients who are refractory to all forms of CMM move up on the treatment algorithm for pain interventions.
