I am 3 weeks post op and have a hard lump on my cheek and on my neck. What is it? (Photo)

I recommend you talk about the issue with your surgeon.  They will be able to evaluate it better in person, and perhaps do something to make it go away (drain a fluid pocket, for example).Best,Dr. Michael EpsteinMAE Plastic SurgeryNorthbrook, IL

Hello,

This might either be a seroma or a haematome. If it doesn't get infected, it wouldn't need any further treatment and is likely to resolve on its own. In either case, I would wait for about 6 months first prior to considering further treatments.

it appears to be scar tissue, however, hard to tell unless its examined in person. The good news is that you are only 3 weeks from surgery, so areas are still healing and improving.   I suggest you follow up with you surgeon to evaluate and treat this further.
