question: My son just had his wisdom teeth removed at 11am today.  He has taken 1 hydrocodone-isprofen 7.5-200 tablet at 3:40 this afternoon it is now 8 hours later He also took 1 tablet of pencillin at 7pm.  I noticed his lower lip is slightly swollen.  His upper lip is normal and he has not other symptoms.  Should I be worried about an allergic reaction?
