Fissure/Piles/Hemmoroids. Lemon water?

I am suffering from fissure since 23rd September.  From last 4 days I have started taking Confinex 2 mg 1 tablet per day,  Muvmend laxative 15ml after dinner and deligistic ointment to apply twice a day.  I had given Sompraz L too as I have gastric and heartburn.  But I stopped Sompraz because it used to kill my hunger and stomach used to feel very much stuffed.  After started taking these medicines,  day 1 and day 2 I went to 🚽 twice. I stopped Sompraz on Day 3. But now, My stomach feels very much filled. I feel like throwing up all the time.  Even water is also not gulpable.  I went to 🚽 once on the morning.  Then I have got this tight chest,  and a feel as if I need to go to toilet but enough amount of pressure is not coming.  And right after my first bowel movement,  I feel very weak, my back hurting like anything,  stomach feels totally full and I feel like throwing up all day.  Please help me.  My chest is also feeling tighten after bowel movement. May I have lemon water?
