Hi there
i never had anything like this but a few days after I was discharged from hospital ( on a Sunday) after my skin sparing mastectomy with insertion of tissue expander I felt like my breast was going to explode ( hard to describe really) , I had my surgery at St Vincent’s Private here in Sydney and my plastic surgeon said if I had any big concerns out of office hours to present myself to St Vincent’s Emergency and ask for the plastic surgery registrar .
I did that and saw the Registrar and he assured me it was not infected or anything to be worried about .
I guess the issue is how alarmed you are about it if you feel presenting to your local hospital is required .
I felt a little silly at the time about presenting myself to emergency where people were having heart attacks etc but I had worked myself up into a state and was glad I did it.
Not sure if that helps.
