Hi clk2137. It’s unfortunate that you’ve had to wait so long to get a definitive diagnosis. The drug your podiatrist prescribed (pentoxifylline) is a blood thinner that improves blood flow, especially in small blood vessels. If it helps to reduce your Raynaud’s symptoms, great. If not, there are other medications you can try. The meds most commonly prescribed for Raynaud’s are calcium channel blockers (CCBs), especially nifedipine and amlodipine, both of which come in an extended release version taken once per day. Finding the right medication (greatest benefit and fewest side effects) can take time.
