I have a bruised feeling on my right knee cap. There is no bruise and I have not been active as of late so it's not from running. What can be causing?
Bursitis. It could be mild pre-patellar bursitis. Not a serious condition.
On my right knee at the bottom of knee cap running along the outside of my knee are a series of bruises, ranging in size from pea to dime what happend?
Purpura. Assuming you didn't have an injury that would have caused this unusual pattern of bruising, you may have a condition known as Henoch Schonlein Purpura (HSP), an inflammation of the blood vessels. We don't know what triggers HSP and don't have a specific treatment for it. It usually goes away on its own without ill effects, but, to be safe, you should see a doctor. Best wishes.
