[/INST] HI, Welcome to Chat Doctor, I read your query and I appreciate your concern regarding this issue. As per its allergic reaction after insect bite / Bee Sting so do not worry. If I will be your treating doctor I would advise you to- Take simple painkiller like Acetaminophen 1000 mg after meal-Take Antihistamine like cetirizine 10 mg at night-Do icing of affected area-keep your foot elevated. Report to hospital if:> Condition remain same after 2-3 days> Any unusual symptom appears> Condition deteriorates.> There is difficulty in breathing. Hope so it will be helpful. You can write again in case of any query or follow up. Wish you good health. Regards </s>
