It also acts as a shock absorber to soften the impact on yourjoints.
Bursitis can be classified based on its location.
There are about 160 bursae in your body.
The degree of pain you experience depends on the extent of your condition.
When irritation occurs, the bursa reacts by producing too much fluid.
The extra fluid causes inflammation and additional pressure on nearby areas in the knee.
It is also common in overweight, middle-aged females.
This can be done by using a needle and syringe to extract the fluid for analysis.
Treatment
Treatment for pes anserine bursitis usually begins with conservative measures.
If necessary, the treatment also involves therapy for an underlying cause.
Pes anserine bursitis is considered a self-limiting condition.
The length of time it takes to handle the condition varies.
Six to eight weeks of stretching and strengthening for most patients can help reduce symptoms.
Without treatment, pain and inflammation can increase, weakening the muscles and tendons surrounding the knee joint.

Taking proper precautions can help you decrease your chances of having this problem.
