Hi . I Used The Lotriderm Cream And My Toesich

Hi . i used the lotriderm cream and my toesich went, so i thought, i will go back get another subscription for another tube to completely get rid of this ich wich have not come back since i finish the first tube.
but as soon as i started the new tube, it was as if i smered my feet with the disease again, i cant even put on shoes. and when i checked the new tube has got a different oarrange label,
