Fissure problem just not healing.

Hello. I have fissure problem since the last 2 years. Till the last year, the problem was under control and it troubled me like once a week only. Since the beginning of this year, my fissure problem has got worse. I am experiencing consistent pain since the past few months. I last consulted a doctor about 2 years back when the problem started. I was prescribed anobliss and lacti fibre. Even at this moment I am taking fibrous fruits and healthy diet along with plenty of fluids. I am even regular with anobliss and lacti fibre as well but even after tremendous hard work, I suffer pain and discomfort every day. This doesn't seem normal because there is no problem in my diet so then what would it be? Please help me out with this and guide me as to how can I get rid of this problem permanently? What are the permanent solutions you would advice after reading through my present condition. I will be grateful if you help me out. Thank you!
