Hello,
Since it appears swollen till date & you are experiencing pain and discomfort if you stand too long, you need to get an X-Ray, CT, MRI done. Get clinically examined by an Orthopedics. Swelling is indicative of
fracture / hair line crack or
injury / tear of the ligament / tendon,
cartilage or
patella, etc. You are suggested not to strain your knee or legs unnecessarily. Avoid strenuous exercises for the time being. You can apply pain relieving ointment or sprays for temporary relieve. Take
Combiflam (one SOS when needed after food) for relieve from pain. You can wear 'Knee support', it should help you feel better. Do not neglect, neglect will lead to worsening of symptoms, improper healing, visible deformities, limited movement, etc. You will be treated as per your reports of CT. MRI & X-ray.
Hope I have answered your query. Let me know if I can assist you further.
Regards,
Dr. Nupur K, General & Family Physician
