###Human: Kindly suggest some solution for sudden knee pain. ###Assistant: Hello. Thanks for writing to this platform. You have written sudden onset pain in the knee region since morning with no history of any injury to the knee. Also, I want to actually know whether there are any associated signs or symptoms of any inflammation like skin redness, swelling, local warmth, etc? If it is just a localized knee pain with no associated symptoms, my advice to you will be: Do not hesitate to contact me should you need any further information/SOS (as necessary).
