Piles Constipation and Rectal Spasm.

I never had constipation in my entire life. I started gym two months ago and since last month I started having Whey protien scoop and boiled chicken breast to increase protien intake in body. But last week I suddenly got constipation and hard stools for 2-3 days which led to small anal fissure and I observed its a small piles too. Now I have stopped having protien and only have moong dal, fruit vegetables salad, isabgool seeds. Since 4-5days I am facing tremendous rectum spasms for 6-7 hours. I cannot even sit since days. Yesternight I couldn't even sleep due to rectal spasm. I try to sit in warm water but it isn't helping. I consumed Arsh Kalp for three days and pilex 3-4 pills daily since 2 weeks but this rectal pain isn't going.
