Yes,
And what you are describing is close to the WORST kind of allergy after anaphlyaxis. It's called angioedema and in it's worse case scenario your throat could swell and cut off your air.

Are you SURE it's the atenolol? More often implicated in angioedema are the ACE inhibitors! Food allergies can do it too though drugs seem to be the usual cause!

Do your lips feel puffy and swollen?

If the reaction gets worse try some Benadryl or chlorpheniramine maleate (both antihistamines.)
