I guess it is an aching sharp pain. It is also very sensitive to touch. I can not touch the upper part of my patella without feeling terrible pain. Any type of leg extension causes pain. Depending on the amount of force used to extend my legs is the amount of pain. With increased force the pain increases as well. This must have manifested over the 5 years of playing without taking any breaks. It is not so much that there is burning but, at times my knee will be much hotter than the rest of my body. I can touch it and feel a noticeable difference.
Thank you for the reply
