I am sending the answer so that you can see it when you come on line.
If you have any query after reading it, please ask.
There can be swelling of bursa.
Bursa is sac of fluid present here.
The swelling can occur from trauma, repeated kneeling down in work or sports.
Sometimes, there can be an infection.
Arthritic conditions can also predispose.
He needs to keep it at rest & elevated now.
Please apply ice wrapped in towel.
It can be applied for 15-20 min 3-4 times a day.
He can take antiinflammatory analgesics like motrin or naproxen, if there is no other contraindication.
If the symptoms continue, I would suggest to get an examination by doctor.
The fluid can be aspirated, steroid injection into bursa would help.
In case of an infection, antibiotics can be needed.
I hope this information helps.
