Urgent help, guys.....seriously, what does IT feel like if ITS gonna happen???

[jmoore10]

Hey guys
Ok, I'm scared shitless and this has been going on for almost 12 hours. Need the input of like-minded people so I can get some perspective. My stomach feels really weird and has pretty much felt the same non-stop all day. It's not indigestion, IBS or my ulcer. It's a persistent feeling at the top of my stomach above my belly button-like a contracting feeling but it just stays contracted/tight (doesn't tighten then release). My throat also feels weird. Not the usual throat n* but more like it's closing.
The good news I have no other symptoms-d, fever, etc. Plus, although the feeling hasn't gotten better, it hasn't gotten worse either-it's just kind of stayed the same. But the idea of food doesn't appeal at all but I can't eat when I'm scared anyways so that doesn't mean much.
So my questions
-is this what it feels like when ITs gonna happen? I honestly don't remember what true n feels like-please explain it to me!
-is this how an SV starts out? Feeling weird for 12+ hours and then suddenly BAM it gets worse?
-should I feel reassured that I'm no worse than I was this am or does this not really mean anything?
-has anyone else ever felt this feeling that I tried to explain? If so, what was it? I have a myriad of stomach issues that I can
usually identify but this doesn't resemble any of them.
I could actually handle feeling this way if I knew it wasn't going to lead to IT.
So, I'm so sorry for the rambling, long nonsensical post. I managed to muddle through work without any serious meltdowns,
but now that I'm home, my mind is running wild and I just need someone to help me make sense of this bullshit.
Thank you to anyone who made it this far!
