A 17-day fast likely caused dehydration and constipation, leading to piles. For immediate relief, you can use a topical ointment containing Lidocaine (for pain) and Hydrocortisone (for swelling and itching), applied 2-3 times daily. Additionally, take a stool softener like Lactulose syrup or Psyllium husk (Isabgol) at night to prevent straining. Avoid pain relievers like Ibuprofen if there is bleeding; use Paracetamol instead. For non-medical relief, sit in a warm water bath (sitz bath) for 15 minutes twice a day and slowly reintroduce fiber and plenty of water into your diet. Please consult a doctor if bleeding is heavy or pain persists.
