I Have A Severe Swollen Lips, Very Rashy, Painful, Burning

I have a severe swollen lips, very rashy, painful, burning and seeping yellow fluid. Also having headaches, feeling very under the weather. I saw a dermatologist she says its an allergic reaction. Called it Angioedema, this is the 3rd time I have had this happen since November. My upper lip is huge, lower large as well, very itchy, sore & painful. The doctor gave me Fucicort cream and Celestamine tablet every 6 hours.
