Never assume: If you ever had a true anaphylaxis to any sting, never assume it goes away. You should be carrying a epipen for self treatment after exposure & seek medical care after injecting it. This episode shows your need to seek out an allergist that can confirm or exclude your risks for the future. If they find no evidence of risk, fine, if present you should have plans in place to manage any sting.
