I have read your query.
You should get x-ray of affected knee in AP and Lateral view and skyline view and send me report. If report is normal then to rule out soft tissue injury
I will advise you to get MRI
scan of knee .
Till then you may continue RICE treatment and take 1 tab aceclofenac+serratiopeptidase
three times a day by discussing it with your doctor.
I hope it helps.
