Of course LDN doesn’t treat Raynaud’s just like it doesn’t treat neuropathy, but it does treat the chronic pain associated with neuropathy, at least for me it has. If you have chronic pain with Raynaud’s, it might work for you. LDN was prescribed for me by my previous neurologist. Unfortunately, she left the practice. My new neurologist wanted to take me off LDN because she wasn’t familiar with it. Never even bothered to ask how it was working before saying that. My PCP now prescribes LDN for me. I wonder how your rheumatologist knows it won’t help you? Did she cite some study? It certainly would be an off label use just like it is for neuropathy. You might want to try another doctor.
