Does it ever happen that panic attacks (and by extension, panic disorder) develop from another condition? I started having panic attacks about eight months ago with varying frequency and intensity. I’ve never had some of the most common complaints, like feelings of choking or having a heart attack. Mostly I get very dizzy and spacey, along with a panicked feeling of course. It’s sometimes hard to follow conversations or even keep my balance. I’ve also started having blurry vision (akin to nearsightedness) and sometimes cloudy vision. More recently I’ve been getting shaky too. It used to be a slight tremble at most, but now I occasionally have people ask me if I’m alright or comment that it’s not that cold out because I look like I’m shivering. This doesn’t necessarily happen during a panic attack either. Sometimes I’ll be laying in bed trying sleep or driving to work when it happens. I know these things can be symptoms of panic and are common side effects of medications, but they don’t seem to correlate with changes in dosage or starting/stopping a med. In addition, I’m just wondering (maybe even hoping) if it’s not uncommon for people to have panic attacks as a result of other underlying issues. I’m going back to get blood tests done soon (my gp has been on me about it for months, but it’s hard to find a day that I’m both off work and also feeling up to it). Last time I had them done everything was more or less normal, but that was over a year before all this started. I keep telling myself that there must be something else causing me to feel this way, because like I said, I don’t seem to experience panic attacks quite the same as most people. It’s also concerning that my prescribed benzodiazepine stops the panic, but a lot of the other symptoms persist (like the blurry vision, dizziness, and extreme fatigue despite it being the smallest dose). Is this something that happens with any kind of frequency? In truth, I’m sort of hoping there’s something else going on that is a little more… definitive, if that makes sense. Thanks.
