Hello,
Egg shaped lump on the knee cap commonly occurs due to
bursitis. It may occur due to other causes like baker's cyst,
skin cyst, lipoma,
benign tumor, etc. It can be bursitis you are suggested to take rest and do not overuse the affected area. Apply ice to reduce swelling, application of dry or moist heat, such as a
heating pad or taking a warm bath may ease discomfort.
Sometimes, the fluid in the bursa can get infected. If this happens, you may need antibiotics. Take anti inflammatory for relief. Get clinically examined to detect
abscess, cyst, tumor, lipoma, etc. You will need to get a few tests, investigations or biopsy done if needed. You will be treated with medicines or recommended surgery if required.
Take care. Hope I have answered your question. Let me know if I can assist you further.
Regards,
Dr. Nupur K., General & Family Physician
