hi moms. i am sorry you've suffered with rsd for so long. i have never tried ldn so i can't help you with that but i have been on gapapentin/neurontin and pain meds since diagnosed with rsd five years ago. i have found that they have helped me manage my rsd pain a little better. i did have brain fog and dizziness due to the side effects from gabapentin during the first few weeks after taking it but the symptoms have lessend a little since then. i still have some brain fog and memory loss but find that it's worth it for me because it helps manage my constant rsd pain a little better. but everyone who has rsd reacts differently to the procedures out there for rsd. i hope that you find a dr that can help you find what works for you so that you start to feel better soon. take care.
