Well, without an evaluation it would be difficult to identify the cause of knee pain
in your case. With DVT
ruled out other possibilities that may need to be considered include infections, inflammations, tendonitis, bursitis, fractures, patellar dislocation, injuries to the internal knee ligaments/ menisci, infections/ inflammations, arthritis, cyst formation, bone growths/ masses, nerve injuries etc. I would suggest consulting an orthopedician for an evaluation and appropriate management.
