You should visit a doctor or colorectal surgeon if piles are not improving, if they're causing pain or if they're worsening. I've had painful piles before and also experienced one that needed to be surgically treated by one Dr Dennis Koh because it was already thrombosed.
Dr Lau Chee Chong is highly recommended. You are always in good hands and you can visit his clinic Ear Nose & Throat Centre at 3 Mount Elizabeth, Suite 14-11 (14th Floor)
Is better if you visit Dr Lau Chee Chong who is a Senior Consultant who has a clinic that is well-equipped for almost all ENT procedures. See his clinic ar Ear Nose & Throat Centre at 3 Mount Elizabeth, Medical Centre Singapore
