Having strange ligament type tightness in neck, never had before. 5 weeks post op smart lipo. Is it normal? (Photo)

I noticed after swelling went down that I had a strand from chin to neck that was very hard, painful and swollen and very tight.....Almost like the muscle, ligament was cauterized from the smart lipo and it now has reattached but is much tighter then before...?? Mind you I never had these strange bands before smart lipo....
