question: I fell and landed full force on my knee on the pavement about 8 days ago. Other than the scrapes, I have had trouble putting weight on it when kneeling etc. Walking has gotten easier. But after long days it can ache pretty bad. It is very sore to the touch still and the pain can be intense with the slightest touch. It feels warm to the touch and the bruising is fading and turning yellow now. Do I need to see a doc?
