Anal fissure healed but itching. Back?

I had itching and pain in anus, so the doctor said it is fissure. I took a month homeopathic medicines and did sitz bath and ate blan food. It healed. But constipation still came n went. So I went to a physician. They suggested some medicines which m taking.. five dosages are left. Now, all was okay.. but sometimes I get a bad itch in anus. It sometimes happen after bowel movement.. sometimes anytime and gets better on its own or after I put some ointment. I m eating healthy.. spices m taking but in moderation. I have no pain or bleeding in the anal region. Just in my right lower back. I m very stressed as to why m having this itch. Is my fissure coming back? Please help.. I m not able to find any satisfactory help. N going to doc in current situation is not an option.
