  • 58 year old lady with t7 pain
  • pain 9/10

Unresponsive to:

  • trial of multiple opioids,
  • corticosteroid taper,
  • gabapentin/pregabalin,
  • duloxetine,
  • amytriptyline,
  • multi compound pain creams, and lidocaine patch


  • thoracic transforaminal blocks with lidocaine and dexamethasone – incomplete relief
  • pulse radiofrequency ablation of the T7-T8 dorsal root ganglion
  • 42 degrees for 120 seconds at the T7 and T8 level – without needing repeats
  • got 80% relief, depression remitted and she went back to work
  • still fine 6 months later

Comment – when pain is severe, most drug measures have little effect. Indeed, in neuropathic pain, response to meds is seen in only 23.7% ( I have wrote  about that  prior) cases.  I would do semineurolytic lidocaine 5% injections repeatedly to numb the intercostal nerve levels, and inject local steroid into tissues,  but obviously pulse radiofrequency bested that.

This had been done before:
