hello, my sister had an injection in her left thigh and it hit a nerve, after it she had pain and felt numbness in that leg. its been 3 weeks and she cant walk right and also cant sit, just lay down, the hospital made ultrasound and they told her that one of the nerves S1 is damaged a bit and they suggested for MRI.. they set the date for too long.. should we wait or what to do?
thanks
