Hi,
sentinel pile is associated with fissure in ano. its a skin tag hanging out from anal verge. usually its asymptomatic but become painful if it gets infected and inflamed. Get examined by surgeon for ur condition. take stool softener, anti inflammatory and antibiotic drugs. take soft diet, plenty of water, dont strain while defecating and keep the area clean and dry. u can also try additional thing. like take hot water in a tub add salt to it and sit in this tub for 4-5 min in such a way that sentinel pile should be in contact with water. it will reduce inflammation and swelling. take care bye...
