[|Human|] Hello Dr. I have a bump in my right knee. I just noticed today. Its right over the knee cap area. It feels like a sack of fluid, if I press it, no pain but its like bubble and can feel that fluid is moving in side. I am scared, hope it is not tumor. Please advise.
[|AI|]  Hello, Thank you for using ChatDoctorI read your question and understood your concern. I think you should not be worried as I think it is a prepatellar bursitis, an inflammation of the bursa above the knee cup maybe due to overuse or friction or your profession (kneeling often). It is not a tumor but a cyst with liquid that needs to be emptied with syringe from the doctor and wrapped up with elastic bandage, so it does not repeat. Some Ibuprofen will help you for one week. Important is for you that it is not a tumor, and you should not be worried. Wish you quick recovery.
