I have Subacute Combined Degeneration of the Spinal Cord caused by a severe b12 defiency not picked up for about 10yrs, I am on fortnightly injections without them I am toast.
The condition causes me to have a episodes of paralysis in legs hand and arms which last anywhere from seconds to minutes.
I am now having a very worrying new symptom if I do walking for any length of time my legs collapse below me without warning.
The muscles in legs when I stand up are like steel
I do have a powered wheelchair which is controlled by my chin but sometimes I just like to go for a short walk, anyone with any similar symptoms.

Have you had your blood work done recently? What is your
B12 level?

Most of the people here who use the oral form daily, have levels of 1000 or higher.

Rose who posts here occasionally had severe damage and she
used to say her recovery was very slow with slips backward.
