What are some common reactions to bee venom?

Most reactions are mild.  You may see redness, mild swelling, heat and itching in the area of the injections.  These reactions are expected and are part of treatment.  Such reactions can last from a few minutes to 2-5 days and are self-limiting (go away by themselves).  At times, flu-like symptoms may occur lasting several days. These are considered normal—they let you know that the body is going through a fighting/healing response. It is best to do nothing and just observe and tolerate the reaction, allowing the body go through the healing process.
