I have pain in left collarbone/shoulder 2 weeks PO TT with lipo. Should I be alarmed?

I am 15 days PO from a TT with lipo. I have been experiencing sporadic bouts of pain in my left collarbone/shoulder region, that can get pretty intense and then resolved as quickly as it appeared. I have had 2 c-sections and experienced the same kind of pain under my collarbone(in which the maternity nurses explained this was not unusual and is caused by having and opened abdominal cavity) , but those instances resolved within a day or so PO. So my question is should I be alarmed?
