A member asked:

What are some possible reasons that my lips tingle during double red blood cell donation?

Preservative: It is attributed to the preservative solution in the system, which i believe can cause a mild reduction in calcium level (why they often offer calcium-based antacid to counter it). It usually resolves on its own after several minutes, and the antacid can speed the process.
