I am a healthy 39 year old woman. For 4 weeks now, I have had a few stomach issues. From the belly button up, I feel various levels of irritation, sometimes a pinching feeling, sometimes burning, sometimes just plain irritated feeling. When pressing around the belly button quite firmly, it is tender. My stools are normal, I don t feel nauseous and there is no blood in my stools or urine. I do have quite a lot of gas and burping. I have no fever. Any ideas? Thank you so much for your time!
