Thanks for posting your query.
With the available described symptoms, there could be possibility of Anal fissure
or thrombosed piles.
As you have positive family history of Colon cancer
, this possibility should also be kept in mind but this is not associated with anal pain.
You should consult with internal medicine specialist/ general surgeon
and should go for thorough check up.
You should also go for complete blood count
, blood sugar, serum electrolytes, and thyroid profile.
You should take plenty of water, high fibre diet and laxatives containing lactitol and isapgula.
You should perform increased physical activity to maintain gastrointestinal mobility.
You should also go for colonoscopy
for better clarification.
