Hi I understand your concern. chronic pain can be treated with different modalities. Management is depend upon site of pain. Minor surgical correction in nerve root supply will decrease pain if site is accessible to surgery. for that you have to consult pain specialist. Medicines like TCA can be beneficial. Amitryptiline or dothepin is choice in chronic pain. avoid methadone as it is opioid derivatives and highly addictive. Underlying psychological stress and its assessment also give good results. consult psychiatrist and pain specialist for better assistance. I hope i have answered you query. happy to help you further. Thank you.
