Maybe: It sounds like you may have patellar tendinitis one on side. This may reflect a tightness or weakness in your hips or hamstrings or other subtle anatomic variant that makes you predisposed. Treatment is a period of rest, appropriate stretching, ice, anti-inflammatories, and eccentric strengthening directed by a trainer or therapis. Other modalities, such as ultrasound, may help. See a doctor.

Tendinitis usually: Very difficult and frustrating condition for those of us who exercise. Rest, anti inflammatories, refraining from squatting , running , stairclimbing for four to six weeks is often required followed by pt. It is usually just one knee. Yes, i empathize as i had this and there is no quick fix. Most do resolve. If not, i would hang in there and see an orthopaedist.
