allergic reaction to ibprofen?!

i have had a sore dry throat for about a week and i took ibuprofen. yesterday and it helped. i took 2 at 1 another 1 at 6 and another at 10. i randemly wokeup and my mouth is really dry and kinda feels swollen. like my cheeks. im not having a hard time to breath but my throat is bothering me. ive taken ibuprofen many times in the past with no reactions. what should i do about it. should i be worried about my mouth feeling a lil swollen. this is also 3 hours after taking it last. i also had some ricola original at about 9 for sore throat. what should i do?. take benydryl. o i just looked and under my eyes are slighty puffy. im 19 years old and its 3 am what should i do
