I Got 1wasp Sting On Each Of My Forearms At
Steroid shot is not necessarily needed
Detailed Answer:
Hello, I'm Dr. Branch, thanks for using 'Ask A Doctor' service.
There are basically two types of local reactions from a wasp sting, an uncomplicated local reaction, which has an area of redness and swelling up to about 5 cm. It sounds like you are already using the usual treatments for these, using cold compresses can also help as well.
Some people get larger reactions, which can typically get up to 10cm in diameter. Sometimes steroids are given for these, but it is just for symptoms of swelling and itching, and the sting reaction should resolve and is not dangerous if you do not take steroids.
Otherwise, it doesn't sound like you are having a generalized allergic reaction, but if you do notice any swelling in your lips or mouth, or you are having trouble breathing, you should go to the ER immediately.
I hope this helps.
Please let me know if you have any questions, and I would be glad to discuss it with you further.
