I am experiencing unexplained falling, no fore warning, unable to react by putting my hand out to protect my face and always falling forward. I have broken my wrist and bruised both knees, then broke my nose, today I bruised my right eye socket. no numbness, tingling. it is like my head is filled with helium or just air as I am not dizzy just cannot feel anything from neck down. My history includes breast cancer four years ago at 31 yrs. had lumpectomy, chemo and radiation, since treatment I have had severe neuropathy in my feet and legs, neuropathy is not present when falling occurs.
