Mi shebeirach

Visiting my friend who suffered a life changing injury while he is the hospital. I am the only Jew. Can I say this prayer if I’m by myself ? I’m seeing him for a few days. I’ve read conflicting things. Toda

Edit: just want to clarify that usually I’d wait for that thread where we can ask whatever we want About Judaism but I’m not in town for long. Didn’t meant to jam up this subreddit with another question that’s easily answered. So thanks for your patience.
