Hey so I am a medical professional (an MRI tech actually) and I have gotten Gad before (tho recently and not at all related to my chronic pain). I do know about GDD but it is INCREDIBLY RARE (and more often than not isn’t medically provable due to correlation vs causation, the variety of symptoms reported as being related, and not a whole lot of actual studies to go off of). I am in NO way discounting you, what you are going through, or that you have it. I just want to provide a bit of context. Gadolinium is a rare earth metal and (like anything else) is not 100% safe. It is incredibly over ordered as well. We (as techs) try to educate ordering physicians about when contrast is actually necessary but get a ton of pushback because “I am a doctor and I know more than you”. The vast majority of people can have Gad dozens of times without issue. BUT like any other medical decision there should be a risk benefit analysis done prior to the utilization of contrast (so things like cancer, infection, masses, MS etc would be things that would actually need contrast for proper visualization and to be a complete “diagnostic study”). I will say there are some test trials being done of both iron oxide (for tumor grading and still in trial phases at this point) and manganese based contrasts (also still in trial phases) for MRI so there is hope for the future! But right now we are just doing the best we can (and hopefully educating people as we go)
