Bleeding in stool (2 times in 1 month)

I used to be very healthy before covid in 2020 Oct. After that I lost 15 kg(gradual decrease-1kg/2month) in 2 years. I am having haemorrhoids type symptoms since last year Feb 2022..never had bleeding in stools but mostly had constipation for 1 -2 days and then passed stool mushy type ..this cycle of constipation and mushy stool continued for 1 year till 2023 Feb . From , Mar'2023 to today, I have been passing normal sausage type stools. Bt I find blood on my fingers 1-2 times in a month. And in the last 8 months, I have developed this habit of cleaning my anus by inserting the finger(2cm in depth). If I don't , it doesn't get clean because the shape of my anus is somewhat distorted after covid .I have no pain in abdomen area but have frequent farts if I drink milk . I burb a lot if I eat citrus fruits or sour things... every is normal in blood report except eosinophils which is 8-9( have  history of elevated esonophils 6-7 since birth) hsCRP-0.45 ;haemoglobin -15 ;kft normal;sgpt-61
