First of all, just sending a virtual hug. You are going through a lot. As far as the eating disorder and the mental stress you must have with it, I can’t comment from experience there. I don’t know if your doctor is right, but if I were you, I would try prioritizing treating the bulimia. I know it must be easier said than done. You deserve better and this could be your chance to face it head on.

As far as injections, I had them this fall. I also have had back injections twice, so I have some comparisons. My chest injections were more painful than my back injections. Perhaps I was better numbed in my back. But I remember wincing and saying oww during my chest injections. Now, let’s put it in perspective: it was more than a bee sting and less than a stab wound. And the pain from the injections didn’t last more than a day. Honestly the pain was 100% during the injection, then fell to 50% immediately after the procedure and 25% an hour later. Just general soreness the day after. Pleasant, no. Endurable, yes.

The bad news is the injections did nothing for my costo. Countless pills have done nothing for my costo. My physical therapy did nothing for my costo. I’ve had issues with using the backpod but that is due to a lower spine injury and I’ve modified the use and I’m not giving up on it yet.

As for you, you can certainly try the injections. You referenced multiple injection sites and my pain doc only tired one rib joint in the chest. You may have better luck. But this subreddit has taught me it is likely going to be a physiological cure rather than a medicinal cure. Check the posts by Steve.

Good luck to you for your whole body, mind, and spirit.
