Definitely does not sound straightforward given all the things they tested and excluded. It also very atypical and medicating specifically for this would be unusual. That said it sure sounds like it perfectly treats the root problem. If you have symptoms like Raynauds and POTS (note that POTS can be hard to demonstrate, so may be less convincing to a doctor) then Amlodipine or similar may be helpful. If you take it and you feel lightheaded when standing up, or have trouble with exercise or fatigue, you probably don't need it and it isn't good for you. You may have more consistently high blood pressure rather than transient spikes if you don't have POTS, or if you don't react immediately to cold temperatures. In that case an angiotensin blocker like Telmisartan may help. It can take weeks to become effective, vs Amlodipine should show effects in just a few days. If you have high blood pressure then just telling your doctor you want Amlodipine or something will probably be enough- convincing insurance will be harder. Amlodipine can be used off-label for Raynauds. If you don't have particularly high blood pressure and haven't systematically tried to exclude causes it will be harder to convince your doctor. They might let you try it for a bit to see if it helps, and the generic isn't too expensive.
