@insanepain acupuncture treatments is a journey. It’s not a few treatments. The good news is that you say it helped. That is key. Why did you stop if you were getting positive results? I was having my ‘episodes’ every 2 weeks. Back to acupuncture for treatment. Like your Lyrica that isn’t lasting, so you up it. Acupuncture allows your body to heal itself verses meds that just mask pain.
Maybe give acupuncture more of a try. I’ve been having Acupuncture treatment for 3 yrs and my ‘episodes’ are gone and I have slight tightness in shoulder blade/ ribcage area that Turmeric and Boswellia take care of just a side note: I’m not associated with any acupuncturist- just a happy recipient of the treatment and works for me. Blessings to you and pray that your upcoming Lumbar Sympathetic block works. (((hug)))
