I got a bee sting and it was swollen for a week and it was very itchy, could i be allergic to bee stings?

Allergy is relative: The normal body response to a sting includes localized swelling at the site with redness. It can be transient or last a few days. Some respond with greater swelling and redness that can involve extremity swelling. If a sting triggered abdominal pain, cramps, a feeling of being lightheaded or worse, you have a worrisome response & need an evaluation for be sting allergy.

Management: Your symptoms indicate a mild allergic reaction. If stung again, you may develop a similar or worse reaction. I have attached a link for more information: http://www.webmd.com/allergies/guide/insect-stings For mild itchiness, an anti histamine is usually part of the management.
