I am so sorry. I agree tell your docs. That is my fear falling cause sometimes I feel like my legs would give out. At the start of this my ankles were really weak from lack of being on them. I have built up more strength and range of motion from being on them. I still fear falling. My neuro said it just feels that way but won't happen. I am not so sure. Well feel better and I hope at least you got some good stuff shopping
