Hi, thanks for writing to HCM.
As you have been on pain medications since many years, there is a high possibility for you to suffer their adverse systemic reactions.
I suggest you to try RADIO FREQUENCY ABLATION which is said to give significant relief from pain in patients with Chronic back pain
. Its effect may last anyway between 6 months to 2 years without the need for taking daily pain pills.
Hope this information is helpful. Good day
