I slipped and fell on my knee around 10/26, 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
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 don't 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.
