My symptoms (numbness in my feet) are worse after sitting and when I first get out of bed in the morning. I do not feel the numbness as much when sitting or lying as I do when standing up after sitting or lying. Mine started all of a sudden 2.5 years ago, and no "smoking gun" cause found yet. Fasting glucose a bit high (104) but A1C is OK. I have low B12 but I take shots, and B12 fine with those. I have a bit of a lower spine problem, but experts looking at MRI do not see that as a cause. I am overweight with BMI at 29 so I need to work on that -- have actually gained wight recently and feet feel worse so that is an indication. Also looking into is possible sleep apnea. I have been taking B vitamins for a long time. Just started Alpha Lipoic 2 weeks ago, will see if that does anything. I take 2 one hour walks each day, which I love and actually makes my feet feel a bit better. I wonder why the walk makes feet feel better. I know it lowers blood sugar (I have measured before and after and it drops by around 20). I also know it increases circulation, but doctor says my circulation is fine. "When I wake up my arms have fallen asleep." << I also get that sometimes.
