Hi. I am 32 years old, male, from Germany. Since 3 years now I'm in severe pain constantly, radiating to the legs, lower back, etc. - I have a large sentinel tag and behind that at 6 'o clock there is a very painful, swollen and sometimes inflammed area that's the source of my pain. I have tried many ointments, but they only help for a short time. After taking a photo, comparing it to pictures online and to the symptoms described, I am 100% sure I have a chronic anal fissure. But the Doctors in my country are unable to diagnose it. I've had surgery before because they thought it was hemorrhoids, then they thought it was prolapse, nothing helped and I'm only in more pain now. What can I do? Currently I am using Diltiazem ointment 2x daily, but it only helps if I don't sit down for more than a few minutes a day. I'm a university student - I have to sit down for hours to hear lectures and write my papers...thanks.
