I am 4 weeks neck lift and lipo post-op. I have had a lump under chin for a few weeks. My PS advise me to apply hard massage to the area 3 times a day he said it’s scar tissue. I have done this and it’s Made no difference yet. Also some swelling along the jawline on one side. The swellings are not hot orRed. I’m going back in 3 weeks to see my PS. I’m just worried. Is this usual and if it will settle down with time. Any advise is appreciated.
