The inside of my anus is tight making it difficult for bowel movement, there s also a tear which occured first due to constipation, I ve dealt with constipation by drinking more than 2ltr of water a day n eating more fibre and exercising, also eating lot of fruits, but now I experience terrible pains because the inside of my anus is swollen and even the stool has this funny shape which implies that it cant go out straight, The Doctor prescribed senokot pills, anusol bullets, paracetamol n other pain killers, but nothing is working, please help me
