Does gingko biloba help? It is for circulation. Can you manage it with exercise like running or lifting weights? And for short term, do you apply heat to help draw blood through areas? Even just a stretching routine? Feverfew or cayenne for the migraines? The blood that can't go into your legs is probably backing up and the pressure is causing the migraines - propranolol? It sounds really interesting and I hope you find things that work to relieve the symptoms while you try to find something more permanent. And with something so systematic maybe acupuncture could help. And massage. Or would massage make it worse?
