I've had itching inside my stomach for years-it got a little better for a year-2 but has gotten worse again. possible cause and especially treatments?

Some thoughts.: there are several possibilites. cannot say in your particular case, but generally, odd symptoms in that area occur in up to ONE in THREE adults on any given day (Mayo Clinic Textbook). You'd think it would be psychological but proton pump inhibitors like omeprazole work in 90%, fake drug 25%. Hiatal hernia, motility, reflux is theorized as cause.
