RhyothemisI finally took a picture of my hand after washing in warm water. The turning-red thing has been going on for a couple of years and it was much worse when it first started - but I could never remember to take a picture back then. I get a bit more brain-foggy than usual when it happens. I think it's erythromelalgia. It used to burn and hurt, but not much, if at all, these days. My feet used to do it, too - either triggered by taking a hot shower or when working in the heat outdoors. That doesn't happen anymore. Maybe the low dose naltrexone helped, or maybe it was just time.
I got the LDN Rx online after reading this case report. The patient had worse symptoms than me (1). I asked for the LDN based on other chronic pain and eczema, since I had diagnoses for those and they are recognized indications for LDN.
I noticed her 2nd and 3rd toes are a bit fused, like mine. Not quite syndactyly. There's another case report on a baby boy with an SCN9A/Nav1.7 mutation who had 2nd and 3rd toe syndactyly along with pain insensitivity. His mother also had the mutation and
2nd and 3rd toe syndactyly, but she had pain hypersensitivity. I have wondered about the difference in phenotype being due to sex differences.
Under 'Treatment' in the 2nd case report, naloxone is discussed as a possibility, but no information is given as to whether the patient was given naloxone or his response.

Erythromelalgia is a rare condition that may be associated with a variety of underlying conditions and can be refractory to therapy. We report a case of a patient with mast cell activation syndrome (MCAS) who developed erythromelalgia and responded to low dose naltrexone (LDN).
