Need advice..

Hello... I am 15 months out of surgery and I have been feeling pretty good.  This weekend I worked out 1 1/2 hr yesterday and today I went to my first bike trail ride with a friend of mine and rode 10 miles!!!!
I am achy all over...

Anyway..my stomach feels sore (not talking about muscles, although they are sore too because of the exercise I did) however..it feels almost like upset stomach.. Don't feel like eating at all or drinking anything.

I am preparing a hot tea to see if it soothes this feeling.  It almost feels like nausea...

I havent' eaten anything today that will be upsetting to my pouch.

Any suggestions??? thank you

Are you pregnant?
