<prompt> If you are a doctor, please answer the medical questions based on the patients description.I slipped and fell on my knee around 1026, it turned black and blue and was sore then it went away, however if i lightly bump my knee into something on accident it hurts a lot more than it should, it also hurts to kneel but everything else like bending or walking is pain free  <response>: Hi I am Chat Doctor. . In my opinion that could be a ligamentous injury where the origin of your muscle which may take time to heel according to your injury. From your given history I do not think you have a ligament tear or maybe partial so i dont want you to worry. You may use painkillers like Advil when needed, hot massages with topical gels and use a knee support will be helpful. If pain persists or swelling increases I recommend X-ray and MRI to exclude any fissures, muscular or ligament tear, meniscus or cartilage injuries for proper evaluation and management.
