24 hrs constant gnawing BLEH. Help?

[KarMar]

So Since last night I've had a constant, gross gnawing bleh feeling in my stomach. It feels like I'm going to have d* but I haven't and it's been almost 24 hrs. Sometimes I feel a nasty gurgling, but not all the time. It started after I ate a cupcake but I've never had "indigestion" that's lasts this long. I'm really nervous because it feels similar to this horrible sv I had 3 weeks ago (minus the d). I'm scared it's part of the same thing and now not going to go away. But I had 2 weeks of feeling totally normal, so I don't know why it would come back now. Any encouragement?

if it's been almost 24 hours then it's probably not a sv*.
What did you eat before the cupcake and how long before?
