Hello and welcome to HCM.
Sorry to know about this incidence.
Clinical scenario you described is due to
allergic reaction to bee sting.
If I were your treating doctor I recommend,
-continue taking
anti histamines like cetrizine or loratidine for 3 days .
-Ice compress wrapped in towel on bitten part every 2 hours.
-Application of
hydrocortisone ointment locally for 3 days (prescription drug)
-Have adequate rest and plenty of water intake.
-Avoid intake of caffeine,alcohol or any sedative.
-Report immediately to physician if you experience swelling of lips,breathing difficulty,diarrhea,
abdominal pain,severe itching all over body.
Hope it will get better in 3-4 days.
Thanks and regards.
