Nifedipine
raynaud's syndrome
"Raynaud's primary syndrome diagnosed 1997. Nothing happened until 2011 when I had a blood clot in my left calf. My toes started to turn purple and hospital had decided to amputate my L leg 3" below knee. I went online and found Nifedipine XL. Had my Dr order it for me and in 2 weeks it calmed my pain in foot so it healed. All the skin peeled off with some toe nails and today I'm on 60mg once daily. Now, I've noticed that whenever my body has a stressful event-migraine chronic (botox) helps so much. But, when I do get  a migraine that happens when my next shot is close to due date (every 3 months) I'll get an aura with migraine and my Raynauds will kick in more with the itching at first. Don't scratch-running water over it."
