During TA, 9 acupuncture needles (Seirin 0.25 · 50 mm) are inserted at GV20,earShenmen,LI4,LI11,SP6,LR3,GB34,and bilateral ST 36. Needle insertion depth is approximately 2 cm for all TA points except for DU 20 and ear Shenmen, which have shallower insertion depths. All needles below the neck level are manually manipulated to elicit De Qi sensations.

SA participants experience a non-skin penetrating pricking sensation at 9 non-acupuncture point locations, sham intervention did not penetrate the skin and was designed to not elicit De Qi. somatosensory component generated by this procedure would be likely to be less than the skin penetrating-TA protocol that elicited De Qi. The sham locations were within similar body locations as the TA points; however, the SA location is not on known acupuncture points or meridians.

Acupuncture is a type of treatment where thin needles are gently inserted into specific parts of your body. It's often used to help with things like pain, headaches, stress, and anxiety.

We hypothesize that patients randomized to TA treatment will have a statistically greater change in pain after the final opioid challenge compared to the initial opioid challenge, as compared to patients randomized to SA treatment(p-value set at 0.05).

patients' response to pain interference over the past 7 days as assessed by the Fibromyalgia Impact Questionnaire in both patient groups to ensure a similar response to TA and SA as reflected in prior studies. The minimum value is: 0 and the maximum value is: 100. A Higher score on the FIQ indicates a worse outcome, meaning greater impact of fibromyalgia on the individual's daily life and overall functioning.
