I was shopping last week and my knee started bothering me it got worse as I had to keep going! When I go home my knee was swollen and there was a small hole about the size of a pin head on the front of the knee, when I soak it in warm water it drains a clear fluid that feels slightly sticky only once did it have a brown look to it. It is hot to touch and it seems I cant get all the fluid and as soon as I get some to drain it fills the knee cap back up?
Hello, The Chat Doctor.  Based on your details, I cannot tell if there is pus coming out from your knee which is a sign of infection or the liquid is clear like synovial fluid which is arthritis. The situation is serious, and I would recommend you to see an orthopedic surgeon as you may need treatment starting from antibiotics to surgery for washing out the knee. If you don't treat it quickly the infection may spread around and will be more difficult to be dominated. Hope I have answered your query. Let me know if I can assist you further.
