Hi im dr.hema physiotherapist.
I had gone through your query.
As per above symptoms, Any joint popping or cracking that is associated with pain may indicate damage to the articulating surfaces of the joint. Such pops and clicks could be due to tissue damage.
If you hear joint pops and clicks with no associated pain in the joint, you don't need to worry.
So I would want you to consult an orthopaedic doctor for direct evaluation.
In mean time continue RICE at
injury site.that is
Stopping any activity and resting is the first step in RICE, then rest, elevation and ice.
Keep your other joints active that is ankle and hip.
Hope this helps and guide you in taking decision.
Please write back in doubt.
Im happy to help you.
