With the available described details, there appears to be possibility of persistent constipation
induced anal fissure
Passage of hard stools may cause injury at anal verge.
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 & movicol. Passage of soft stools will help in recovery.
You should perform increased physical activity to maintain gastrointestinal mobility.
You should also take proton pump inhibitors along with prokinetics.
Combination of liquid paraffin
and glycerol is most effective in constipated cases.
