@dmp19651989 Weakness in arms and legs can be caused by spinal cord compression in the neck. This was the situation I had because of bone spurs and a ruptured disc digging into my cervical spinal cord at the C5/C6 level and I did not have any issues at the nerve roots; it was all spinal cord symptoms causing everything. I could bend my neck forward and send a big electric shock down my entire body. I had surgery at Mayo that resolved all of it.

Would that perhaps be an option for you to have your husband evaluated at one of the Mayo campuses? That also depends on if your insurance is accepted by Mayo. I wasted 2 years chasing doctors who wouldn't help me, and it would have been better if I had just come to Mayo first. The neurosurgeon at Mayo was the sixth surgeon I consulted and the only one who got everything right in the diagnosis and the fix for it.

Here is the insurance information page if you wanted to check.
