Because it's associated with kneeling a lot.
The infrapatellar tendon, also known as the patellar tendon, is located below the kneecap and connects the patella to the shinbone. It plays a key role in enabling extension of the knee joint and is important for activities like running and jumping. Injuries to the infrapatellar tendon can result in conditions like patellar tendonitis.
Bursitis
The common name for sub patellar bursitis is "knee bursitis."
Shin
It may cause symptoms identical to bursitis
Knee bursitis is the inflammation of one of three fluid-filled sacs in the knee. This is commonly caused by injury or strain, including continual pressure, directly hitting the knee, or frequent falls.
The bursae around the hip joint are deeper, and swelling is not obvious.
A bursa is a closed, fluid-filled sac that functions as a gliding surface to reduce friction between tissues of the body. Bursae is plural for bursa. The major bursae are located adjacent to the tendons near the large joints, such as the shoulders, elbows, hips, and knees. When a bursa becomes inflamed, the condition is known as bursitis. Most commonly, bursitis is caused by local soft-tissue trauma or strain injury, and there is no infection (aseptic bursitis). On rare occasions, particularly when the immune system is suppressed, the bursa can become infected with bacteria. This condition is called septic bursitis.
I have sharpe pain in front of my leg from ankle up through the knee
The two bursae of the knee that have the highest incidence of irritation in sports are the prepatellar bursa and the infrapatellar bursa. The prepatellar bursa, located in front of the kneecap, is often irritated due to repetitive kneeling or direct impact, commonly seen in sports like wrestling and volleyball. The infrapatellar bursa, situated below the kneecap, can become inflamed from activities that involve repetitive jumping or running, leading to conditions like jumper's knee. Both bursae are susceptible to overuse and trauma, making them common sites of injury in athletes.
Thank you very much. I am 21 years old, not really a jumper or athlete type girl. The pain is basically on that lump only. And its becoming whitish from its centre. Not exact white but comparatively whiter.
