Wascaly, I too am 74, with severe peripheral neuropathy from CIDP, an autoimmune disease. I have terrible numbness in my feet and legs, poor balance, dizziness and fractured my femur five years ago. I certainly have the fear of falling! I use a walker in my house and am very careful. A few things I find helpful: I attached a small flashlight to my walker that sits next to my bed so I can easily slip into my shoes and see my way to bathroom in night without waking my husband. I also find keeping my feet warm with socks helps the numbness and cold feeling. PT for balance and gait training can be very helpful. When possible, I hold onto or lean against the counters or furniture when standing to make me feel more stable. I also have several motion sensor night lights around the house so I can see clearly where I am moving. It really is hard to put up with these symptoms and limitations in mobility, but I am very grateful to not have the pain of PN that many others have. I also am thankful I can still walk in my home and around my yard, using a w/c or scooter for longer distances. I hope your new Dr is helpful and will work with you to maximize your functioning and treat any treatable contributors to your numbness, such as B12 or folate deficiency.
A positive attitude and focus on what you can do goes a long way in warding off depression caused by the physical declines of aging and disease. None of us signed up for this hard reality!
