|I recieved Scenar treatment on a sprained ankke with pulled ligaments. My therapy lasted aprox 30 min...near the end of the session I suddenly became nausiated, had cold sweats, was hyperventalating and disorientated. I was suffering from shock! This has never happened in the past with treatment. I was hoping to understand why this may have happened. It was very frightening, but I have to admit that my ankle is doing better than it should be. The swelling is minimal and I am putting weight on it only after 4 days. I do have to say that the episode has left me slightly aprehensive of continuing therapy.
