For the 30+ years I've been alive, I've watched my mother suffer with eczema. I've seen the devastating effects of medicines with harmful side effects that don't cure; but actually extend the period of suffering. I watched as physician after physician prescribed medication for my mother, but never addressed her poor diet or her allergens (the cause of the flareups). My mother never drank water. Soft drinks were her water substitute and her diet was worse. This is why her immune system was so unhealthy.
Through heredity, my nieces acquired this immune sensitivity and suffered severe (total body) eczema flareups in their infancy. Because I was determined not to let any of those harmful medications touch my nieces, I took it upon myself to care for their skin and find healing through natural means. I was confident that I could gain more success; due to the fact that I knew that the cause of my mother's eczema (unhealthy immunity & allergen/irritants) were never addressed by any of her multiple physicians. I knew that if I had addressed the cause, the healing would follow. In two weeks time, my nieces severe (total body) eczema flareup was completely gone without the use of harmful medications. I identified her allergen/irritant, removed it from her environment, applied a natural skin care system (vitamin/mineral enriched lotion & baby wash), and addressed her immune health by providing the proper nutrition and supplementing her deficiencies with a liquid multivitamin for infants. My oldest niece has been eczema free for five years, and the middle niece, for four years.
I'm so passionate about sharing what I have learned, because I know that it works. By simply applying common sense wisdom, my nieces have lived an eczema free life for a majority of their lives despite the fact that conventional medicine states there is no cure. The cure for eczema is a healthy (balanced) immune system. You can restore health to an immune system through the proper nutrition.
You confirmed, through location (middle of the foot), my suspicions regarding the liver, colon, kidney connection. Your body is saying that you need a cleanse/detox. I personally recommend the All Natural Internal Cleanse by Nature's Medicine. This is an excellent cleansing system for the novice of internal cleansing/detox. I've personally used this system and have found it to be the best out of several that I have tried. You can find out more about this system at the allnaturalcleanse.com website.
Also, stress releases cortisol which promotes eczema flareups due to the abundance of histamine activity that takes place. Chamomile is a natural stress reliever; and is also known as a natural anti-itch herb. This tea provides the soothing relief without making you drowsy the next day. Also, increasing your vitamin C intake will be beneficial; in that it is a natural anti-histamine. The abundance of histamine release is what equates to the overactivity in the immune system which manifests in an eczema flareup. The Burt's Bees Bath Crystals are a good soak for the feet. In addition, an Epsom Salt soak may serve you well. Burt's Bees also has a foot care line that may want to look into.
The reason I keep speaking of the Burt's Bees line of skin care is because this is the line of skin care that we used to bring healing to my nieces skin. This is just one of many natural alternatives that you can choose from. If you live in the U.S., I strongly suggest you take a trip to your local Whole Foods Market where you can view, first-hand, the variety of options that exist.
To get your immune system back into balance, I suggest you take a look at the wholehealthmd.com website to view the "healing eczema through what you eat section. This is a good reference guide to help you in becoming more familiar with the types of deficiencies eczema represent and how to go about replenishing those deficiencies through the proper nutrition.
I'm glad you stumbled across this site and I hope that your turn around to good health will come soon. Also, worry blocks your mind from hearing answers. In the quiet, while you're soaking your foot or just sharing quiet time with your children before putting them to bed, you may be surprised to find that the answers you were searching for regarding that worrisome problem comes from the most unlikely sources and in the times you least expected.
