I’ve tried a variety of drugs to help me cope with the pain,  and they aren’t providing enough relief. I don’t feel ready for surgery; are there any other treatments available to me?

Acupuncture. Acupuncture may be adjuvant treatment along with your pain medications. In particular auricular acupuncture may help pain.
Yes. There are several classes of medications to relieve pain. There are narcotics, antidepressants, anticonvulsants, lidocane patches, electrical stimulators, intraspinal injectons etc. In chronic pain, often many modalities need be used, including psychotherapy. Talk to your doctor to see which ones might be right for you.
