I just joined this site and wanted to write down my experience. I've read a lot of posts and see people suffering from very similar symptoms. My symptoms started about 6 months ago. I was working out at the gym and then for the first time decided to dry the sauna and steam room. long story short, I sweated myself into some pretty severe dehydration and ended up in the ER. My initial symptoms were shaking, dizziness, and cloudy vision. The doctors were at first concerned that it was a stroke, but it turned out to be severe dehydration. Ever since then I've been experiencing a myriad of what I believe to be panic/anxiety related symptoms. Dizziness and loss of equilibrium, tingling limbs, sore neck muscles, faintness, derealization and lack of focus as well as heart palpitations and general panicky feelings. These symptoms get me worried that I'm having a stroke or an aneurysm, or will just generally pass out and slip into a coma or something equally ridiculous.
I've been to a doctor for a general check up and everything checks out fine, but it's still hard to shake the feeling that something will happen out of the blue. I know many of you are going though similar situations, and while this is terrible I do feel encouraged that I'm not alone in these feelings.
Anyway, I just wanted to type out my thoughts here. I feel like just verbalizing it helps me wrap my mind around it. I feel for all of you here and wish you all the best!
