nbm, it’s hard to tell from your brief description exactly what’s causing your symptoms. Have you been diagnosed with Raynaud’s? If so, your treating physician can prescribe one of a number of medications that can reduce the frequency and/or severity of attacks; most commonly prescribed are drugs known as calcium channel blockers, including nifedipine and amlodipine. There are also treatments for digital ulcers caused by Raynaud’s, including intravenous infusion of iloprost.
