You seem to report that when you do

  curl -H userAccount:abc http://nginx/xyz

you want nginx to make a request to https://someserver/ including the
http header userAccount; and that nginx does make the request but does
not include the header. Is that correct?

A simple test, using http and not https, seems to show it working as you
want here. Does the same test work for you? If so, does using https make
a difference to you?

    # "main" server
    server {
        listen 8090;
        location /xyz {
            proxy_pass http://127.0.0.1:8091/;
        }
    }

    # "upstream" server
    server {
        listen 8091;
        location / {
            return 200 "request: $request; userAccount: $http_useraccount\n";
        }
    }

$ curl -H userAccount:abc http://127.0.0.1:8090/xyz
request: GET / HTTP/1.0; userAccount: abc
