[|Human|] I have over the last few days felt a tightness in my left knee, I cannot recall doing anything to cause this. I do not have any pain sitting down but when I get up it takes a while like 5 or more steps for it to start working but it feels really tight and uncomfortable and I can only walk with a limp?
[|AI|]  Hello, Tightness at knee is due to spasm of muscles around knee. This can be one of the early symptoms of problem at knee. In your case knee problem can be - -An cartilage abnormality(with its structure or a metabolic problem)-Effusion at knee-Ligament or meniscus problems At present I will advise you to take rest and avoid excessive movement. You may use a knee support like knee cap for this. You may have good analgesic like aspirin, ibuprofen or paracetamol for this. Early problem will resolve with this. If problem still persists then you should consult to your orthopedic doctor for treatment. Hope I have answered your query. Let me know if I can assist you further. Take care
