Fissures after c section. For fissures?

Hi Doctor, I had c section three months back. I am suffering from fissures from one month. I am taking looz and isagbol. I was taking looz 50 ml for one week and the pain reduced. But then I reduced the dosage to 30 ml since I am not sure if it's safe for breastfeeding. The pain is again increasing day by day. I had been taking water and fiber. When I increase water and fiber intake, I am going motion 3 to 4 times a day. So, I had to suffer the pain for 3 to 4 times. The first bit of motion is always painful no matter how much water and fiber I take that day. I am also taking lactare tablets and galact granules daily for milk supply. Can they be the  reason for fissures? Please suggest how the fissure problem can be completely gone.
