Is it safe to bust a blood blister on a diabetics foot?

No, please don't: See your doctor and have your feet evaluated as soon as possible, any open sore can cause a serious infection and should be monitored.

Podiatrist.: Best to see your podiatrist for that--there might be a wound underneath they need to treat, and if there is any infection involved, they would want a sample of the blister fluid.

Not on Diabetic: The smallest problem can lead to a much larger problem. Have a podiatrist take care of it.

Don't do it!!!: Bacteria love to thrive in blood. This can be treated in a doctor's office, but don't do it yourself at home. You could just develop much larger problems, primarily infection.
