the past week or so my tongue has been swelling up. I'm alergic to psuedafed (the decongestant) but i haven't taken any since last year. That is the only thing i can think of that makes my tongue swell like this. I don't have any lesions or bumps or any other kind of side effects. I'm not alergic to any food or animals. The first time i my tongue swelled up last week i had just woken up and hadn't ate anything. Could you please help me narrow down my search of what could be the cause of this "Mysterious" swelling?
