1) Frequent Nursing & Compress
Here is a good home remedy for a blocked milk duct.  The best preventive measure you can take is to simply nurse your baby frequently in order to empty the breast.  By doing this, you are going to be more comfortable and also keep the inflammation down.   Whatever areas are sore should be massaged.  After you are finished nursing your baby, you should firmly massage your breast.  Start massaging your breast at the top and go toward the nipple location.  It is also helpful to place a slightly warm compress to your breast before you begin nursing your baby.  Using the compress will help the milk completely drain from the breast.

Vitamin C

A  good blocked milk duct home remedy is to have different nursing positions.  Try to cradle and/or hold your baby in a different way while nursing it.  This will help you to empty the milk ducts.  If you already have blocked milk ducts and are experiencing pain; then, hold the baby in a way that positions its’ chin in the direction of the sore area.  This will position the baby’s suckling toward the clogged duct and will help to heal it up.

2) Blocked Milk Duct Home Remedy with Vitamin C
Your diet can influence the prevention and/or treatment of having blocked milk ducts.  If you take vitamin C in ample amounts; this will help to prevent blockage, and/or aid the healing process if the ducts are already clogged.   Also, in the event of clogged ducts, and feelings of pain, you should have a hot drink containing lecithin and Echinacea. This helps to take away the pain and to unclog the ducts.
 
During this time of nursing, make sure that your bra is a right fit and allowing you to breathe properly.
 
If you want to prevent the development of blocked milk ducts; massage your breasts in circular patterns working inward toward the nipples.  You can put a warm wet cloth or heating pads on your breasts to make the circulation better.  Also, how you sleep really matters.  Always be sure to sleep on your back so you avoid putting pressure on your sore breast.
 
The type of clothing that you wear should not be tight fitting as this can cause pressure on the milk ducts.  Tight shirts and bras need to be avoided.  Also, the type of material is important.  Cotton is a much preferred material as it allows more breathing and is more comfortable.  The synthetic materials should be avoided.   Try to exercise a little, walking and possibly jogging would be good.  You must maintain a good diet.  Also, get plenty of rest.  Be sure to drink lots of fluids throughout the day and don’t overly exert yourself. These are good remedies you can do at home to avoid getting or to help treat blocked milk ducts. Of course, if you have blocked milk ducts and are unable to unclog them, then get right in and see your doctor.
