Someone else with pernio! I haven't felt so normal in a while!
Pernio is actually how I was diagnosed with Lupus. The sore was actually cut off of my toe for a biopsy. So I'm not really positive what the procedure is to care for it. SleepyInSeattle seems to have given a great response though (thanks!)
The only thing that I can add is that I started taking Amlodipine for Raynaud's last year after I was diagnosed with pernio. Amlodipine has seriously changed my life. My Raynaud's was debilitating and with the meds I don't have any discoloration and more importantly I don't have any pain. It's unbelievable.
Be careful toughing out the pumps (the things we do haa) and I wish you only the best!
