Hello. I am an avid blood donor but this last time, a few days after donating and having removing the bandaid in a timely fashion, I developed a rash . It iches and started out as just small raises and is now slightly pink and irritated. Should I contact the blood bank or could this just be a random reaction to the bandaid? It just seems strange because I ve donated a lot before and this has never happened. Thank you for your insight.
