unexplained knee bruise

[kfair1]

I have had a lot of knee pain at night. This is my left knee. Today I wake up with a huge bruise on my right knee. I have no idea where this bruise came from. The bruise does not hurt, but the knee is aching. Suggestions???

Hi
Welcome to the MedHelp forum!
Sudden onset knee pain can be due to ligament tear, bursitis, meniscus injury or due to dislocation of patella. Any injury or inflammation can cause bleeding from fragile capillaries and this may appear as a bruise. Please consult an orthopedic specialist.
Hope this helps. Take care!
