I pivoted (toe planted, heel moved outward), and felt discomfort on the inside of my knee and couldn't extend it fully or bear weight on it. It got a bit better with NSAIDs and rest today, but is now back. 10 days ago after a deep tissue massage, I was diagnosed with an irritation of semintendinosis/pes ansirine area (the tendon was catching), but, by ultrasound, the bursa was not inflammed. Am really hoping this is not a meniscal tear.
