answer:This very well could be just severe panic attacks. They present in some strange ways sometimes. Did he giver her any medication for this or did he just diagnose her and send her on her way? If he gave her medication, have the episodes decreased in frequency or intensity since she began taking it? If she has some reason to believe it’s not panic attacks, or just isn’t sure, she should get a second opinion. There are a few disorders (mental health and otherwise) that could cause similar symptoms. It’s nothing we can diagnose over the internet, and I’m sure you know that. I’d advise her to see her doctor or another doctor if these are either worsening or greatly affecting her life. There are so many factors that one would have to take into consideration before placing a name on this phenomenon. I hope she finds answers and sufficient treatment. I’m sure these episodes are terrifying for you, and certainly not pleasant for her either.
