I had surgery 4 months ago. Now I feel foul smelling sometimes. Today I consultant other surgeon for second opinion and he says there is high chance of infection again that may be in bone or around skin. I am sharing the photo please see and suggest what should I do. One thing that I want to ask, the yellow fluid seen inside is pus or post operation fluid or wax. My surgeon say it's normal it's not pus, but this dr. Is saying it is pus.
