Thanks for writing to us.
Sometimes as a normal phenomena, fluid (synovial fluid
) that lubricate the joint release bubbles which pop and crackle with movement. This occurs very commonly after a period of inactivity or during certain movements. I am not sure if this is what you have, but this is my most likely explanation to your symptoms.
You don't need to worry if there is no associated joint pain; but you have to do some conditioning exercises to improve the overall integrity of the joint - stronger muscle will take the weight of the joint and help to reduce the pressure on articulating surfaces, thus preventing any damage to the joint.
I would suggest getting this evaluated by an orthopedician for an accurate diagnosis and appropriate management. You may get the X-ray of the area affected under his/her guidance to see any arthritic changes
Wishing you good health...
