Hi, Thanks for posting in HCM. I understand your concern. Ordinary bee stings that do not cause much of an allergic reaction. Multiple stings or an allergic reaction, on the other hand, can be a medical emergency that requires immediate treatment. In your case, kindly wash the area with soap and water, and apply cold compresses or ice pack. For pain, you need to take an over-the-counter painkiller like Ibuprofen. For itchiness, take an antihistamine like Levocetrizine. You can also apply a mixture of baking soda and water or calamine lotion on the lesion to reduce the swelling. Avoid scratching the sting area. This will worsen itching and swelling, and increase your risk of infection. Gradually, your symptoms should subside and you should be better. There are no side effects associated with bee sting and taking medication such as Metoprolol. Hope the information provided would be helpful. All the best.
