<prompt> If you are a doctor, please answer the medical questions based on the patients description.Hi, I fell onto my knee cap on Wednesday. I can barely walk on it, when I am still it is painful but when I move it feels as though there as something behind the knee cap like a swelling, but there is no swelling at all. from what I can see. I find it hard to bend my knee without it being painful, there is only a small bruise on the side of my knee and the pain is not getting any better since I fell on it.  <response>: Hello, It can happen after a fall. Most probably it is just a sprain, the fracture is unlikely. As of now, you can use analgesicsanti-inflammatory combination like diclofenacserratiopeptidase for symptomatic relief. You can also apply ice packs for faster recovery. If symptoms persist better to consult an orthopaedician and plan for an MRI scan. Hope I have answered your query. Let me know if I can assist you further. Take care Chat Doctor.
