It's a possibility, but numerous other things could also be the reason, and of course I'm not qualified to make a diagnosis. Even if I were, I couldn't do it online. Here is some information on conversion disorder, if you're interested.

For the record, some could say conversion disorder is "all in your head," but that's not the same thing as "it isn't real," or "you're faking it." In fact, deliberately faking it has to be ruled out before they can even say it's conversion disorder.
