hello. i m a physiotherapist working in reputed hospital in mumbai n even runnibg private clinic from past 3 years. one of my patient is suffering from epidural haemorrhage at the tooracic level of spinal cord due to the adverse effects of blood coagulant-varfarin.
i worked on him for 2 years n he started walking with walker but there is no bladder bowel control.
patient was affordable for taking stem cell treatment so he took that from dr. geeta shroff-new delhi. but there is no change in his condition. i dont think stem cells work for this kind of patients. thanks
