Hi there
I would like to suggest you to go for an x ray first and see if there is any injury to knee joint. And take that x ray to an orthopedic doctor. If the joint and bones are normal then you can take some pain reliever and go for physiotherapy treatment for quick recovery.
Next Steps
consult an orthopedic doctor or a physiotherapist
Health Tips
