Some things don't change, such as the necessity for a high-fiber diet, plenty of water, and sufficient exercise.
However, many of the medications used for external piles can't be used for internal piles for a variety of reasons.
First, location is quite important in deciding how to treat piles.
An external pile is on the outside of the body, usually quite near a major nerve band. Internal piles, on the other hand, emerge from delicate mucus tissue on the inside of the body, and aren't generally near extremely sensitive nerves. This distinction alone leads to different symptoms and therefore different treatments for symptom relief.
Second, some medications should never reach the inside of the body at all.
All of the pile creams you see on the market today are specifically for external piles. While some of them may be used for itching and burning caused by internal pile and leakage, none should ever be placed inside the body. If internal piles are causing mucus discharge or fecal incontinence to make your exterior anal area itchy or inflamed, feel free to use any pile cream for the purpose of relieving the external symptoms.
However, never, ever use tubes or applicators to put an external pile cream inside the body without a doctor's recommendation and ongoing care.
Pile creams are designed to deliver medication through external skin, not through internal mucus membrane. Intestinal membrane absorbs everything quite quickly and easily, that's part of its function. External skin has many more layers and is meant to keep most things out of the body. Due to this stark contrast, if you put medication meant for relatively thick external skin on internal membrane, you will in effect be giving yourself a massive overdose of the medication in question. Only medical professionals have the mathematical background to calculate the correct internal dosage of an external cream, which is one of the reasons they went to school for so long and charge the fees they do.
Internal piles only respond directly to internal treatments, such as ibuprofen, acetaminophen, a high-fiber diet, or aloe vera juice drinks. In addition, warm sitz baths can help to improve the circulation in the area and so are highly recommended for both internal and external piles. Sitting on icepacks can also help with inflamed internal piles.
Given these factors you should be able to approach the treatment of your piles, no matter which kind you have, from an informed basis that can make all the difference.
No matter where your piles are, or what condition they're currently in, enough knowledge is out there for you to eventually lead a pile-free life.
