I am 27 years old. I have congenital heart disease name ebstein anomaly. Till now I am taking treatment from cardiologist. In addition to this I have hypothyroidism and constipation. Recently I underwent anal fissure surgery. But once again I am getting constipation problem. I can't able to pass my stool regularly ie it takes 2-3 days to come out and my stool becomes harder which gives me more pain during excretion. Kindly help me in this regard.
