Possible stomach bug?

I know there are lots of "stomach bug" threads on here already, but I wanted some feedback on my specific situation. Really, I'm not for sure this is a bug at all, since I never really have those sorts of stomach problems.

Around mid day Sunday I noticed my stomach felt a little "off", but nothing really major and I forgot about it just as quickly. I had also woken up with a sore throat that day, but it too went away quickly. Monday morning my stomach felt off again and I noticed that my output was much thinner than usual. As the day went on I continued to have a sour stomach....not quite nausea and nothing the kept me from eating, though my appetite was less than normal. Everything I ate seemed to go thru me pretty quickly and output continued to be copious and watery. I am also very tired, mild headache that comes and goes, feel warm but have no fever, have some nasal drainage and have a general "blah" sort of feeling. Funny enough, the only time I felt pretty good Monday was while I was working out!

So now it's Tuesday late morning, and things seems about the same. Of course I'm drinking lots of water, and don't want to take Imodium or anything. Figure if I DO have a bug, it needs to work it's way out of me. But...if it's not a bug, what could it be? I'm not a big fan of taking it easy, but guess I might have to :( Also, it may or may not be related, but I have a small ulcer/canker sore on my stoma. I have seen something like that once or twice before....

It does sound like a mild stomach bug- I'd go the BRAT route, thickening foods, maybe a small dose of liquid Immodium, lots of fluids... this started on Sunday??? I'd give it until tomorrow, then call your PCP. Or GI, really- whichever you have a better rapport with! Good luck, I freak out with lots of watery output myself!

Thanks ladies! Earlier today I was feeling pretty awful....and I almost hesitate to type this....but in the past couple hours I feel like I *might* be feeling a little bit better. I'm still not hungry, but don't have as much stomach pain and I'm not quite so tired. Have been sticking to "BRAT" diet type foods today and lots of water. I really hope I'm turning the corner and can maybe even make it to yoga tomorrow evening! But just in case it persists, I did email my GI and GP with symptoms and asked their opinions. Hopefully I can force myself to rest tonight...after dishes, laundry and animal care!

Thanks for checking on me blueglass! I started to feel a little better yesterday (Thursday). I wasn't as tired, had a little bit of an appetite and my output wasn't quite so watery. Today I have felt pretty much the same as that with a little less tiredness and output steadily thickening. My stomach still feels off after I eat and my appetite is very small, but I figure that will come back soon enough. Luckily I never threw up...but if I had an "other end" it would've been coming out that way I'm sure! :P I was worried about hydration....and found the pedialyte in my cupboard was expired, so I made my own drink with water, lemon/lime juice, a little honey and some fancy salt from Whole Foods that still has all the minerals and such.

I did contact my GI and GP to let them know what was going on and both emailed back saying it sounded like a bug, stay hydrated, go to the ER if I thought I needed an IV and to call if I wasn't feeling better. So...I guess I'm ok....I just can't help but worry that little things are something more, given all I've been through!
