<s>[INST] I am 17 years old and have had a reoccurring knee injury every year throughout my softball season. Normally it takes all summer to heal which isn t a big deal, however I am leaving for the Airforce in August so therefore don t have time to stop exercising and let it heal. It retains water under the kneecap. Also it is terrible pain trying to stand out of a crouched position and walking upstairs. I was told it was jumpers knee however symptoms of this seem to be the opposite of what I have. Normally it hurts going downstairs with jumpers not up like it does me. Also it hurts to run. Which is a necessity to be able to train! So is it jumpers knee or not? Also what should I do treatment wise if I don t have time to stop and rest? [/INST] Hi, thank-you for providing the brief history of you thorough musculoskeletal assessment is advised.Also, the pain is limiting your functional ability of climbing stairs and also from crouched position to stand up. If your physician mentioned a jumpers knee, I will advise to take an MRI scan of the knee as for me, it appears to be a more of a ligament sprain in the knee joint. But only with thorough musculoskeletal assessment and MRI scan the diagnosis can be made. With proper exercises and Rehabilitation program you can have a better knee, and you can join air force as well. RegardsJay In Chat Doctor.  </s>
