I have numbness (loss of sensation) all over my body. From head to toe. Had scans and tests done back in 2015 when it started. Everything is normal. The symptoms only last one week, but it comes back again every month around the same day. I will see a Neurologist once again this coming up August, but I’m pretty sure there will be no concerns. I am so confused to what it could be and it frustrates me feeling the way that I do. It doesn’t affect my walking or movement and I have no pain. It’s just loss of sensation everywhere. What could be the cause?
