There are a few reasons why you might have a big bump below your knee cap on both legs. One possibility is that you have a condition called Osgood-Schlatter disease. This is a common condition that occurs in adolescents, and it is caused by inflammation of the patellar tendon. Osgood-Schlatter disease can cause pain, swelling, and tenderness below the knee cap, and it can also cause a bump to develop.

Another possibility is that you have a condition called chondromalacia patellae. This condition is also known as "runner's knee," and it is caused by wear and tear of the cartilage under the kneecap. Chondromalacia patellae can cause pain, swelling, and tenderness below the knee cap, and it can also cause a bump to develop.

Finally, it is also possible that you have a bone tumor. Bone tumors are rare, but they can occur in the knee. Bone tumors can cause pain, swelling, and tenderness below the knee cap, and they can also cause a bump to develop.
