Lol..yep I had it done ...once..
I also am a long term user of opiates/opioids. I had the acupuncture done to help with horrible migraine that had been lasting for several days plus chronic pain (back, legs, hips). I had this done by an actual MD who also is "certified" for acupuncture at the urging of my pain management doc. Btw, insurance ended up not paying so I was out $150 bucks.
They placed the needles in various places...head, face, arms, feet, lower legs and abdomen while I was laying flat on my back on a warming blanket on top of a water bed type mattress then was also left to lie there for about 30 mins (at which point he came back in, gave a little twist to some of them then left me alone again for a bit). I left my jeans and loose shirt on as he just had me unbutton my pants and lower the waist down a little and pull the pants legs up to accommodate the ones in lower legs. I did remove my shoes and socks. When he was putting the needles in (which was not painful to me at all, he actually was concerned that I had reduced feeling/pain perception because I didn't even flinch when he placed them)I experienced a feeling of extreme relaxation and a tiny bit of head rush. I was excited and thought maybe there really is something to this. I went into it with a totally open mind..willing to try anything for my pain.
So the point to the story is, when I left (and my oldest son had went with me because I didn't know what to expect) I was driving home and all of sudden moved a certain way, had a pretty intense pain in my stomach area. I had to pull over and get out of the car. I lowered my jeans down a little and there were 2 needles he had inadvertantly left in my stomach area! I had moved just right causing my jeans I guess to push them all the way into my abdomen! I immediately grabbed them without thinking by the little tip sticking out of me and pulled them out. My son (LOL) immediately begain to throw up when he saw all of this!
I called the doc he tried to blow it off. I suffered no long term damage but needless to say I will never have accupuncture done again! (BTW, it didn't absolutely nothing for my headaches or pain and the asshole still billed me for it even after that happened!)
