<s>[INST] Hello,I just went to the dentist for a crown and not sure what happen, but when the doctor was putting the anesthesia I felt a sharp pain in my eye, the same side he was working. When he was done I felt my cheek was different, and yes, I have a big lump. Should I be worried it could be an infection? Is there something I can do to relief the swollen?Thanks for you help! [/INST] Hello and welcome.Thanks for sharing your concern.The  lump that you are experiencing now, could be due to locally deposition of local anesthesia.It should diffuse within a few hours or so.Then the lump should go away.It is not an infection.Regarding sharp pain in the eye,it appears unrelated.but if you find persisting symptoms in relation to eye then please revisit your dentist.Also please mention in which jaw the crown was placed upper or lower?so that I can suggest better in this regard.Hope it helps.Thanks.Take care. </s>
