I have very severe quadricep pain in both of my legs. I had a mild cramp wednesday night, then Thursday when I woke up both of my quads were in severe pain. It s very painful to sit down, then stand back up. Friday when I woke up the pain was worse then today it was even worse when I woke up. It hurts to walk, going up and down stairs and moving after sitting even for short periods. There was no direct incident that caused this, no lifting, no moving, no fall. The only thing I can compare it to is when I used to lift heavy weights, it feels like the next day recovery but so much more painful.
