I understand how you feel. I've been feeling much the same.
Does the weather effect you negatively? When the pressure is low and a storm is approaching does your balance get bad?
We've had a couple of weeks of rainy damp and now cold weather and I have been having a terrible time walking and doing just about anything. Whenever I get this way the first thing I check is the weather.
I use a rollator walker (4 wheel kind that you push) and I'd be useless without it. I have no balance anymore. It's just worse right now because of the weather.
Have you asked your Neuro about possibly getting some physical therapy? It might help. I had it for a couple of weeks and it made a small difference. Nothing miraculous but it helped......and I enjoyed the company when the therapist visited!
I hope you feel better soon. Wish I had some answers for you but wanted to let you know I feel the same way.
