Hi i am Dr Ahmed Aly
thanks for using HealthcareMagic site ,
I had gone through your question and understand your concerns ..
In my opinion you may have a kind of
tendinitis or your
cartilage surfaces become more rougher or ligaments tightening .
I do not want you to be worried unless these sounds are painful , you may try to decrease your weight , avoid heavy lifting , vigorous movements , bending your knees for a long time and bad sleeping and sitting postures .
Using hot massages with topical gels of anti-inflammatory and some physical activities like morning jogging will be helpful.
If these sounds became more painful i recommend you visit your physician for proper evaluation and management and prevent further complications .
