Fissure or hemorrhoids in the bum area.

Hello, I'm 41.i have irritable bowl syndrome. I suffer from bouts of constipation on and off. I have had treatment for that with normaxin rt for a few months.i take fibogel fiber powder everyday. Before menstruation I suffer from constipation and the last time was bad.i have pain in the bum while pooping. It is slightly better now but otherwise it felt like a tear and pain. After delivery of a child I have hemorrhoids.i have attached a pic. It's not this bad all the time but it hurts this time. I have mild pain in the area when I apply pressure. Can I use a gel that will help reduce pain and inflammation.Does this need any other treatment. I Walk daily. My bmi is right. I'm 59 kgs ,5'4 tall. Have no other problems. Please advise. Thank you.
