MRI cause of peripheral neuropathy flare up?
Has anyone here experienced a peripheral neuropathy flare up after having an MRI?
Some of my symptoms are headaches, vertigo, painful peripheral neuropathy, but was doing ok on Tuesday. I am not sure yet if I have MS or neuroborelliosis (Chronic Neuro Lyme Disease) both have brain lesions, the size and quantitiy of lesions will finally give me a definitive diagnosis, I guess. I have had a positive Lyme test from tick borne specialty lab, Igenex. But symptoms of LD and MS are so similar it is next to impossible to tell the difference. Need to be sure before starting treatment for either.
Anyway, then I had a brain MRI later that morning. That evening, I felt very warm as if feverish and woke up the next morning with widespread nerve pain.
Has this happened to any of you after an MRI? How long did the flare up last..I am just hoping damage didn't occur. I have had MRI's before, years ago and never had this happen, so I am pretty scared.
I found this out about MRI's:
High-strength, high-slew-rate gradient coils are desired in modern MRI for better image quality and faster imaging speed. However, rapidly time-varying magnetic fields produced by gradient coils induce electric fields in tissue, which can cause peripheral nerve stimulation (PNS).This significantly limits our ability to take full advantage of these high-performance gradient systems. Despite considerable research in this area in recent years, the relationship between PNS thresholds and gradient coil linear region dimensions or gradient performance parameters is still not well understood. In this study, we investigated this relationship.
Thank you in advance for responses.
