[|Human|] I have swelling and redness below the knee for more than 2 weeks. I have had an ultrasound to look for a blood clot but it came back negative. I am now on antibiotics, but 4 days in and no improvement. I am resting it and elevating it and icing it but i m wondering what it could be?
[|AI|]  Your description about the symptoms is highly inappropriate to provide a proffer answer. Diagnosis highly depend on weather it is back of the knee or front of the knee. As well how below it from knee joint. If it is back of the knee [deep vein thrombosis. Bakers cyst] must be excluded. Cellulitis[infection of soft tissue] and bursitis can happen anywhere around knee joint. Treatments are highly depends on cause for swelling. Antibiotics will help if it is a cellulitis.
