Hi,
My mother in law has shortness of breath which is tied up her with neuropathy. Neuropathy can affect the major nervous systems which there are two that control the body. With both I have throat constriction among other symptoms from autonomic polyneuropathy which starts affecting my lungs and heart along with peripheral neuropathy which takes care of the things like legs and arms.
Neuropathy is the interaction between nerve and muscle and brain. For me they are corrupted signals from and to the brain and muscles mostly intermittent but some have become permanent. Worst case scenario the heart can stop instantly without warning when the neuropathy decides it wants to. I have found I have no conscious control over the problem. There is no cure or treatment for my neuropathy know to date. I just have to wait it out and hope the heart is the last organ that will be affected. Touch wood the heart is still good to go, so far! I do have an enlarged heart but always new I was big hearted anyway!
To date the worst it has been for me is paralysis when walking, unable to move the feet or legs. Reminiscent of concrete boots! Stopped dead mid stride for a few minutes, left looking and willing my feet and legs to oblige me with moving, felt like a lifetime, but just minutes. No such luck, scariest feeling so far not knowing if I'm ever going to continue moving or was that it for life. Often my left legs fails to step when commanded and the brain knows it sent the signal so continues the momentum of the stride and over I go. Fortunately the brain still learns and it now has the ability to act quickly and catch myself before kissing the ground. I'm curious why it is alway the left leg though.
I'm constantly learning just how invasive neuropathies can be. You know what it is like when the information input into a computer does not resemble what you expected out and you are left pulling your hair out until it is resolved. Same scenario, mayhem and confusion.
Cheers
