I don't see how this could be useful for much of anyone, especially if you get nervous easily. I don't but I was told after an hour worth of questions and a rather simple infection that I needed to go to the hospital and have surgery and have an IV for condition I've resolved multiple times before and gave details explaining exactly that. I mean what do these doctors do? I was told to go to a local hospital which we don't have since they shut it down over covid. Thanks for the stress!!!
