What causes severe pain in knees?
Patient: I have developed severe pain in my knees when getting up or down from a seated position over the last weeks. I have tried physical therapy for patella femoral syndrome and they have only gotten worse. I am being seen by a pain specialist whom is doing facet joint injections on my back. I see an orthopedic doctor for my knees. I have excruciating pain at night when I straighten my legs out and when I get up. I am scheduled for an mri on both knees. I was wondering if the back injections could ve caused this or what else can it be? Doctor: Dear patient you may be having early inflammatory arthritis of both knees. what us your age ? if you are past 50 yrs osteoarthritis may be likely. I would like to advise xray of both knees anteroposterior and lateral and skyline views. Mri will be more sensitive and specific then xrays. Please take tab ultracet twice a day for pain relief.  You need to consult orthopaedic surgeon with report.
