I don’t believe everything on the internet is a lie (although of course I don’t believe everything on the internet is true either). You have to read it and judge for yourself.

In the case of getting medical advice, there is an inherent bias to finding anecdotes on the internet. The people who post are going to be the people who have something to say. That’s going to be either people who had a life changing positive experience, or who have something to complain about. The middle-ground experience is underrepresented.

However, there is value in anecdotes. The doctor can tell you high likely a given side effect might be, but people on the internet might have a better description of what that experience is like.

I try to take in as much information as I can when I am making an informed decision, including things like asking my doctor, finding anecdotes on the internet, and finding actual scientific papers.
