I have read your query.
It seems to be soft tissue injury
, but to make exact diagnose get xray of knee with thigh in AP and Lateral view and send me the report to exclude any possibility of hairline fracture
Till then avoid running and jumping.
Take 1 tab. aceclofenac+serratiopeptidase
three times a day by prescription.
In future if you wish to contact me directly, you can use the below mentioned link:
I hope you have got your answer.
