Hi there...it looks like you could be suffering from fissure in ano or haemorrhoids. Fissure in ano is more common in this weather, due to increased loss of water from the body, leading to hard stools. You will need detailed clinical examination to confirm the diagnosis. Start taking plenty of fluids, eating foods rich in fibres like green leafy vegetables, raw fruits. Do sitz bath at home. Kindly consult a general surgeon for further evaluation. Treatment will include oral and local analgesics, stool softeners.
