I just had a bone graft done yesterday morning. After the swelling went down, i noticed that there is still this hard bump on my cheek next to where i had the bone graft done. I also noticed this yesterday afternoon as well but just thought it was part of the numbing medicine that was given to me. When i woke up this morning and it was still there, i'm a little concerned. My dental office is closed until Monday. I do have a follow up visit Monday afternoon but I don't know if i should spend the weekend worrying that this bump could be something serious. Any suggestions?

BTW, i am new to this site TIA
