I have lower rib burning

Yesterday I woke up in the morning to this burning sensation in my lower rib area (under my breast). It comes like waves every other minute, it comes burns and then goes. I don't know what it is. It is scaring the daylights out of me mainly because whatever I usually wake up with is gone by the mid to end of the day. But I here I am, I wake up again to the same burning sensation. I am so so so so scared I am thinking pancreatic cancer/stomach cancer. I know its not anxiety related, has anyone had this before? What could this be? Please help me!

Thank you for your reply Tela but its on my left side, I think gallstones and issues with the galbladder are on the right side if I am not mistaken?

Wise words from Sharon!
