In 2018 I was suffering from frequent stool  with some amount of  blood along with mucus for at least 7 days. Thereafter, I consulted gastroenterologist doctor then immediatelyhe prescribed me for colonoscopy . Accordingly my  colonoscopy was done and it's shows non specific colitis . Doctor prescribed me asacol 1200 mg with antibiotics. But the medicines prescribed above was not working. After that he asked me to stop that medicines. Then he prescribed me three types of antibiotics with morease sr which worked for me. And he stopped my antibiotics medication after 15 days and asked me to take morease sr for one month.thereafter it stopped and I was fine. After one year, again I had some cramp and found some blood along with mucus in stool for two days and after that it stopped. So I thought it was not necessary to visit doctor. Shall I go for colonoscopy after how many year I need checkup.plz answer
