Can I increase 20mg. And 10mg at night?

I went to a pulmonary doctor for breathing problems. He gave me a corticosteroid-based inhaler. After using it, I started feeling lung pain in different areas. I used the inhaler for 3 months. When I went back, the HOD said I don’t have a breathing problem and I don’t need the inhaler anymore. But since I started using the steroid inhaler, my lung pain began and is still there in different areas. Then I was referred to a gastroenterologist. He gave me Vasoprazan 20mg once in the morning for 10 days. I also ate very simple food (only dal and rice, no mirch powder). I started feeling better. After 10 days, the doctor reduced the dose to 10mg, and I also started eating food with mirch powder again. Now, my lung pain has returned. I have an appointment with the gastroenterologist on Monday. My question: Can I take 20mg Vasoprazan again for 3 days until I meet the doctor? If yes, should I take 20mg in the morning or 10mg in the morning and 10mg at night?
