This doctor should be sued. For not being ethical. First I have a problem with doctors selling products. Rsd and our pain is not a retail service but a serious medical condition. Is this Dr R a salesman or doctor? Then to sell it to you without taking you on as a patient is not ok. Then to talk about law suits when everyone should be open to giving back feedback both negative and positive is insane. I would think there is some medical board one could file a complaint
With RSD it is important to keep stress down. Which is like impossible but in ways you can anyhow. This just adds stress. Have you looked at other options for pain relief? Ketamine infusions,different meds,some other alternative like HBOT? Has you r husband seen a pain doctor? Is he on meds? Trust me i have times I beg to die from pain too and I know the heart break that has on my family. I know it must be hard for you to watch your husband as well. People do get to a better place with RSD but it takes finding the right treatment. Everyone is different so what impacts one may not anohter. I am very sensitive to weather as well so can relate as I sit hear swelling with high pain from humid/storms.
If I can help in any way I am an email away. Are you in the US?
