Thanks for the query,
Its good that you are taking sitz bath daily.
Its advisable to go for a proctoscopy as many of times internal and external haemorrhoid co exist.
Also I advice you to go for an early surgery.
Delay in surgery often complicates the situation.
Please meet a dermatologist
for final diagnosis and treatment
