I had an infection, not immediately after surgery but recurring and finally a serious infection 12 months after. In no way my surgeon's fault, the major problem was that a persistent seroma created a fertile breeding ground for the bacteria that we all have in our bodies. Heavy duty antibiotics seemed to be doing the job, but my surgeon wasn't satisfied the core problem was dealt with and had to make the tricky decision about keeping on keeping on with antibiotics, or surgery to clean out the infection (leaving me open to possible hospital based infection). Not an easy decision. He went for surgery, and that was the end of the infections (and the seroma). But it's a complex problem - I didn't have radiation (although I sure looked as if I did) and radiation will doubtless complicate the matter more. Some good suggestions have been offered so you need to try and soothe the inflammation first, and then see if there is any improvement. If so, then that's the right course of action. But if not after a reasonable time, then a second opinion is always worth getting. Good luck.
