They get worse in the winter time, but they're cool in the summer. Probably I'm thinking Raynaud's, but I don't want to claim that. I'm open to any feedback you have on maybe how to make it better, fix - physiology, neurology supplements, testing, breath work, etc. I'm open to all of it. Any help is much appreciated.
