10 Causes Of Hives
Reviewed: Dr. Gromatzky
Cause #7: Blood Transfusion
Hives can also be triggered as a response from the immune system. In this case, it’s quite possible that getting a blood transfusion can trigger a fairly serious reaction of hives.
This tends to occur within 24 hours of the transfusion. There are a number of other immune symptoms that may present themselves in this situation, such as a fever, chills, or excessive itching. These problems all generally go away without needing additional treatment as the immune system accepts the transfusion.
