Question : Hello I'm 14 years old and for a couple weeks now I have been having knee pain. A squishy lump appeared right beside my knee cap but is only visible when flexing or bending the knee completely. The pain is full and achy. I'm getting an MRI Thursday but I just want to know what to expect

Brief Answer: Bursitis? Please reply for my doubts. Detailed Answer: Hello, I have gone through your query and understand your concern. I suspect you are suffering from Bursitis. I would like have few answers. Where exactly the swelling is either on medial or lateral or upper or lower of knee in which leg? Do you have any recent fall or injury? Do you have any redness or swelling? Does the swelling appears only on flexion or extension of knee? Do you have any fever? Are you a regular active sports person? Waiting for your response.

Brief Answer: InfraPatellar Bursitis. Rest, NSAIDs, Ice pack Detailed Answer: Hello, I have gone through your photos and query. It's look like Infrapatellar bursitis. Bursa is nothing but a sac containing a fluid that lies between the muscle tendon and bone. You should give rest to the knee joint. Do not flex or over extend the knee. Avoid putting direct pressure on the knee such as when kneeling. Apply ice pack every four to six hours. It may help in decrease the inflammation. If the pain is intolerable, then take NSAIDs like Ibuprofen once or twice daily. Rest to the joint is very vital in treatment of bursitis. Hope this helps. Please write back for further queries. Wishing you good health.
