For you it may be you have a crepitus
Crepitus is a symptom characterized by a crackling or grating feeling or sound under the skin, around the lungs or in the joints. In soft tissues, crepitus is often due to gas, most often air, that has abnormally penetrated and infiltrated an area (for example, in the soft tissues beneath the skin).
In a joint, crepitus can indicate cartilage wear in the joint space. The term "crepitus" is derived from the Latin, meaning "a crackling sound or rattle." Typically, crepitus is a grinding noise coupled with a sensation in the affected joint. It can be a popping sound that is audible, and can be no less harmfull than it is annoying. If it is joint friction, it can be an indicator of something more serious. Crepitus can occur with or without pain.
If this relates to your problem do a search on crepitus and find out more.
If there is no inflammation, anti -inflamatories are a waste of time.
