<human>: When I shower with warm water and I step out my knees are red and warm and they stay like that for more than 10 minutes. It happened to me also when I was cooking and stading in front of the stove and when I finished and sat down noticed my knees red and warm. Why is this happening?
<bot>: Hello, Having warmth in the knee can be soft tissue inflammation. But we need to consider some criteria here, like knee pain, your age, any knee injury, twisting, etc. Without having a detailed history we cannot tell if its OA or Ligament injury.  Having a detailed history along with an x-ray should allow us to help you serve better. Hope I have answered your query. Let me know if I can assist you further. Jay In Chat Doctor.
