Acidity, Mild sensation in stomach/Kidny

Hello, I had block ear problem couple of week before. So I visited ENT specialist, where she prescribed me tablet to rid the blockage (Potasium clauage 625mg and other r3lated medicine) After finishing the dosage of 4 days. I started feeling itching in my anal area and on other day after gym while returning to home I had redness in stool so I was afraid and changed my food dinner for couple of days only taking fruits at night and applied sriderm over der. However, the itching got rid. but I started hearing growing sound in my stomach area. it's really frustrating specially at night it get worst. After couple days my stool movement increased by 5 times per day but there was no watery kind of stool but felt acidity. Plz help me I really need help. Thank you in advance.
