Hi Dear,
Welcome to HCM.
Understanding your concern. As per your query you have swollen and painful knee . Well there can be many reasons for symptoms you mention in query like Chondromalacia, Bursitis, gout ,
Arthritis,
Osteochondritis, Ton Meniscus , bakers cyst or infection . I would suggest you to consult an Orthopedician and get evaluated and a thorough clinical evaluation and investigations like x ray, CT Scan , blood tests and physical examination etc as per suspected cause can help in diagnosis and treatment can be planned accordingly. Doctor may prescribe anti-inflammatory painkillers, muscle relaxants ,
physiotherapy to relieve and strengthen the muscles,
weight loss and doctor may also prescribe nerve supplement along with antibiotics in case of infection or surgical excision in case of cyst . For now take proper rest , keep your leg elevated while laying down , take
ibuprofen or acetaminopehn for pain , apply warm compresses on swelling and lower your salt consumption.
Hope your concern has been resolved.
Get Well Soon.
Best Wishes,
Dr. Harry Maheshwari
