I am a boy, 23 years old this year and just had an anal fissure surgery 10 days ago. After surgery, I went to the toilet once every 3 days. Every time I go outside, it hurts because the wound has not healed, it is very normal, no bleeding. So far, I see signs of healing, a little itching and can walk normally, but when I go to the toilet, I have symptoms like severe constipation (I sit with moderate force to push the stool out to the anal hole). but then I got stuck and couldn't get out, then I soaked it in warm water and continued to try hard, after 30 minutes I split the seeds until the stool was gone) I gently washed it with warm water mixed with water. salt and soak for another 4 minutes. After that, when I entered, I felt pain and swelling and a feeling of tightness and heaviness in the anus. Please let me know if this is serious and how to fix it after anal fissure surgery?
