Hi, I have been feeling pain in stomach and lower back left side. My stool is not properly emptied by me. I feel like vomiting some times. And right after having anything I. Feel like vomiting and stomach pain. I also feel I have so much in stomach although I don't eat anything. Narrow stools with mucus Is also main concern. And stool color is sometimes black as if it's a very old stool. And I have been in either constipation or diarrhea situation very often. As i live in USA, I have been eating processed foods a lot due to time constraints. And I don't get to get any blood tests or stomach tests done here on insurances we have. Please help me with your thoughts on this. This is the very first time I'm experiencing such issues in my life. Don't know whom to contact here in this country I'm living right now. Everything is expensive and I'm seeking your support. Please provide your thoughts and Thank you
