<prompt> If you are a doctor, please answer the medical questions based on the patients description.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?  <response>: Helloo.read through your query...I must say that its normal and that nothing to be worried in this.lower lip must be swollen because of two reasons1he might have bite his lip without knowing when it is numbevery1 feels to bite2during extraction sometimes the forceps might have slightly caught the lip BCO it numb v cant feel pain at that time but later when numbness is gone it might go for swelling.so nothing to be worried in this.tell him to continue the medicines this swelling will be fine in due course...hope youre benefitted something from this reply.have a healthy day!!!
