I kind of did the splits unintentionally on ice about 5 months ago. Sweeping fist occurred right away and difficulty standing. Applied ice and anti inflamitories. Pain never went away. Progressively got worse. No pain on side and front knee. After long day on my feet pain is extreme behind knee and trave,s down shift. Difficulty getting in vehicle and painfull to drive with knee bent. Relief comes sometimes by standing and straightening leg. Pain pills are the only thing getting me through work days
