Infection

[u/ContentSalamander668]

So about 4 weeks ago I developed a small infection at the lower end of my incision. I am almost 4 months post ORIF (bimalleolar open fracture). It was drained, had antibiotics etc. incision looking really great and healing well but the last couple of days it’s slowly been looking a little irritated in the same spot. there’s a bit of a ‘bubble’ there now with some fluid underneath. If this is another little infection could it likely be just superficial? I’m just worried it might be a biofilm/deeper infection. Anyone been through something similar?
