Motley,
Thanks for the question.
Raynaud's is not typically associated with ongoing vascular insufficiency (continuous purple feet) and non-healing ulcers. I would recommend that you see a good rheumatologist for a thorough assessment. Other diagnoses than Raynaud's should be considered, specifically a vasculitis.
I would further recommend that you discuss the further need of any beta-blocker with your doctor. It might be better to learn to cope with the PVC's while these leg changes are being sorted out.
Hope that helps.
As you probably already know, beta-blockers can aggravate Raynaud's disease, and you are therefore rightly concerned about your condition.
I would encourage you to have that toe seen again, as ulceration in a raynaud's patient is very rare (1% of all cases).
As it has already been pointed out, it is atypical of Raynaud's to continuosly constrict, or be constantly cold. Such signs could possibly suggest other problems such as acrocyanosis, or heart problems. You physician may also wish to rule out any underlying autoimmune disease.

Best of Health!
Don't think I have acrocyanosis as I do have the red, white, and blue color phases, don't have the sweating, do have numbness and
sometimes pain. While my hands and feet are persistently cold they are not persistently blue, just blue more often than used to be. My feet are blue (actually purple) when sitting or standing in one place, the capilary refill is very sluggish. I never thought that beta - blockers were a good choice for me but all the doctors told me not to worry about it. Now that someone has witnessed the circulation problem I guess I am supposed to worry about it. Actually need something done as I am walking on dead feeling feet a lot now and my hands are falling asleep more often also. Thanks for your response. If anyone else has Raynaud's info please post.
