Piles also known as hemorrhoids can be a troublesome illness and therefore it is vital you know the symptoms of piles in order to treat them before they get chronic.
The most common symptoms are listed below:

• Bleeding from the anus - Swollen piles can bleed as bright red blood in drops just after passing a stool, the blood may also splash into the toilet bowl making the person panic about the loss of blood.
  Sometimes the persons undergarments can be stained by streaks of blood.
  
• Swollen piles that are pink and blue coloured can start to protrude out of the anus like a bunch of grapes (Also known as external piles).
  This is one of the most common symptoms of piles.
  
• Sharp pain - Swollen piles can usually create a burning, stabbing or throbbing feeling, which can make the person tired and difficult to sit down and relax.
  
• You might also feel a lump or discomfort in your anus when passing a stool.
  
• Some itching around the anus can also occur.
  
• You may start to get severe pain or aching around the anus and lower rectum, which can mean the piles have become very swollen.
  
• You may also feel as though something is moving down the anus.
  
• Mucus can also seep down from the piles causing irritation and more itching.
  
• You may get a regular feeling that your bowels have not completely emptied even after a bowel movement.
  

These are some of the key symptoms of piles which can eventually lead to severe bleeding and may require surgery if too swollen.
You can go visit your doctor and try to find temporary relief though creams and drugs but you will never cure your piles with these treatments because they do not tackle the root of the problem.
