[|AI|]  Hi.I've gone through your query and I can understand your anxiety. Fluid collection around knees cause localized swelling. It could result from many conditions like overuse of the joints, damage to ligament or cartilage, fracture, bacterial infection, osteoarthritis or rheumatoid arthritis, gout, prepatellar bursitis etc. I advise you to visit ER to, - do a Joint aspiration & the aspirated fluid should be tested for - bacteria, crystals, protein, glucose, blood cells to rule out gout, infection, injury etc. - Do X-ray of affected knee to find out the cause - Take anti-inflammatory Chat Doctor.  - If infection is confirmed, then take a course of antibiotics. - Therapeutic joint aspiration can relieve some pressure in knees, followed by use oral / injection of corticosteroids directly into the knee joint- Physiotherapy Hope I have answered your query. Let me know if I can assist you further. Take care.
