Anal fissure please help 😩😩😩

Iz

Ok so.. I have chronic constipation and all types of digestive problems. I had diarrhea for who knows why from last Tuesday to Sunday, and so now I have a tear on my butthole 😩 it hurts so so bad. I’ve been putting a&d diapers rash cream on in hopes it will do something but it doesn’t seem to help!!

Please help!! Anybody had this before?? What helped?? Or should I just go to the doctor.
