Hi, thanks for your query.
You seem to have developed prepatellar bursitis
also known as coal miner's knee, housemaid's knee, or nun's knee. It is common among individuals whose professions require frequent kneeling. Prolonged and/or repetitive kneeling causes friction and puts pressure on the bursa leading to inflammation of the bursa in front of the knee.
To treat the same:
- take rest
-use knee pads
-you may take anti inflammatory and analgesics for pain
-application of ice locally
If this does not help you may need to consult a doctor for other modalities of treatment like aspiration and rule out infection.
Hope this solves your query.
