I had a muscle stretching in my calf which couldn't been totally seen by the ultrasound equipment of the clinic. The physiotherapist did well requesting a better exam in the hospital but it was useless as they did a x-ray and another ultrasound while they suppose to request a magnetic resonance which can better indicate the level of the lesion.
So, I wasted money doing that as the treatment hasn't changed being done massage in the clinic and stretches at home. I used to compete in amateurs football championship in Brazil being experienced dozens of physiotherapy sessions with totally recovery. Based on that experience I didn't like the methods applied in my treatment as the result was not enough for plenty recovery.
