I've had Raynauds for 15 years or more with many indicators for Secondary Raynauds - extremely high ANA and more. Now I have an ulcer on my index finger under the nail. My dermatologist removed part of nail 3 weeks ago but it's still very painful. He prescribed a trans dermal vasodilator 3 days ago which has done little so far except give me a headache. Any suggestions anybody?
