Chilblains: From the beta blocker or B12?

Remember those weird itchy, but painful bumps on my toes? Well now I know what they are and it's either a complication from the beta-blocker or from low B12.

These little bumps are called chilblains and they occur when you are having poor circulation or if you warm the feet too quickly. Here's a link to a medical website that talks about them in more depth.

I started taking the beta-blockers about a week before these bumps showed up. At first they were very very itchy, but as long as I kept them covered it wasn't so bad. Then I noticed anytime my feet got warm, they'd burn like hell. Not long after this, my left leg started to feel numb like it feels when my B12 is low. I even made a post about the paresthesia returning.

I'm trying to put the pieces together. Maybe the "paresthesia" is from the beta-blocker and the poor circulation is then causing the chilblains too? I looked all of this up and it is possible according to this website.

"Some drugs such as beta- blockers may affect the circulation and cause chilblains"

Darn it. I might have to call the doctor and see what he has to say about it. The beta-blocker is helping so much I'd hate to have to quit it...
