My husband just recently had knee surgery . His swelling
Probably a cyst due to surgical procedure, more details are needed.
Hello dear and welcome to ‘Ask A Doctor’ service. I have reviewed your query and here is my advice.
The symptoms of your husband are probably related to seroma.
Seroma looks like a swollen lump or a cyst which is filled with fluid.
It usually develops after a surgical procedure.
A photo of the lump would be helpful to help me through the diagnosis.
More details that I may need are:
Does your husband have fever?
Does he have pain in the lump area?
Does he feel rapid heart rate?
When these cysts are red they usually have an infection.
So, I would recommend to continue using antibiotics.
I will be waiting for your response to be able to help you better.
Hope I have answered your query. Let me know if I can assist you further.
