Advice needed please

Hi all, 1st time posting. Had a pain in my abdomen for about 10 months, just at the solar plexus area. Went to docs and had a stool sample and blood test done about a month ago. All came back clear. There's a dull ache still there, when I eat it's very uncomfortable and the last 3 days I've had very loose stools. Just very worried it's something more sinister, if my bloods n stool sample were clear am I worrying about nothing ? Thanks so much for reading, any advice greatly appreciated.
