<s>[INST] Hello, I was walking down my stairs and I slipped and banged my knee on the side of the door, it was a very hard hit and for a moment I thought my knee went out of place. It s swollen now and I don t know how to relieve the pain? And I don t know how serious it may be? Advise pls [/INST] Hi there Thanks for your question at Chat Doctor.  Rest, ice gel pack application. Tight crêpe bandage application, limb elevation and mild analgesics like acetaminophen or diclofenac can relieve your pain and swelling in the initial 48 to 72 hours. The swelling will gradually reduce over 1 to 2 weeks. You should be concerned and visit your physician If. 1. You are not able to stand or walk for few steps without pain.2. Furthermore, you are not able to fully bend or straighten your knee(full range of movements). 3.the swelling and pain increases over time instead of subsiding.4. Your knee hurts on kneeling at the end of 2 weeks. Hope this helps. All the best. Regards.  Chat Doctor.  </s>
