I have fallen three times in the last two months i am 70 years old with diabeties which under control..any suggestions as to what could cause these f?

Neuropathy on feet: It is very likely that you have neuropathy in your feet/legs which reduces your ability to feel the ground as you walk. As a result, you don't have same sense of equilibrium/balance as before. Thus, walking on uneven ground/soft-cushy such as rugs can predispose to fall. Please see doc for an evaluation and treatment. Good luck.
