My sister has had eczyma since she was 3 years old I believe. I remember her going to Doctor appointments in various times of her life while we were growing up. Sometimes, it would be worse and then she would get better and it would clear up. My mom took her to get tested for allergies, and then they would say "she's allergic to this, that, and the other thing". So, my Mom wouldn't let her have those things, and she still broke out. We were raised in Eastern Washington, where we had extreme cold winters (when her eczyma would flair up badly in winter months) and hot summers (when her eczyma would clear up). In her teenage years to adulthood, her eczyma would also flair up when she got stressed out. When she was 18-19 she wanted to be a nurse (this was 20 years ago) and she had to wear latex gloves. Her eczyma was the worst I had ever seen it. She found out, she was allergic to latex, so she had to quit and figure out another career choice (this was before polyurathaine gloves, she has since gone back and got her nursing degree 2 years ago).
We have better resources now, then we did 30 years ago. Here are some things she does now to keep her eczyma in "check".
1. Use non-purfume, dye-free, detergent. She uses All "free", she told me the cheaper detergents have made her break out, she doesn't know why. She also uses Bounce "free" dryer sheets. She liked the Downy "free" liquid as well. She has tried the biodegradable, natural fragrance, "green", expensive stuff, and she had a break out. She would love to have her clothes smell nice, but no such luck.
2. Use Aveeno body liquid soaps and lotions. She finds when she "strays" from Aveeno, she breaks out. She has also used fragrance free,hypo-allergenic stuff, and she will still break out. She has even used different baby liquid soaps and lotions with scents, and she will break out. She always uses the liquid soaps, the bar soaps dry her out.
3. She wears 100% cotton clothing, underwear, and bed linens. Polyester blends also sometimes (depending on the percentage of polyester) will provoke a break out. My children would break out a bit when they weren't wearing 100% cotton, I break out in a rash when I wear something with polyester in it. Look at the labels where the tags are. It will say 100% cotton on it. Polyester doesn't let your skin breathe, any percentage of polyester or nylon. My 12 year old will break out in a rash when he wears shirts with spandex in them. Bed linens, you don't think about too much, but, if you think about it, we sleep 8 hours (or we try) a night and spend 8 hours rolling around, sleeping in our bed. She makes sure it's 100% cotton, she doesn't spend a ton of money on high thread counts on her sheets, she does get a higher thread count on her pillowcases though. She also washes her bedlinens in the ALL Free detergent.
4. CREAMS She has tried creams off the counter and percriptions, and stuff from the health food stores. She has told me it's all trial and error. I remember my mom would get excited when she found a new cream to try on her. Sometimes it would work, sometimes it wouldn't. She has used hydrocortizone, and she tends to get the brand names of creams and not generics. She would also give it 4-5 days to see if it gets better, before she will move on with something else. If it gets worse right away, then she doesn't use it obviously.
5. DIET She has told me that it doesn't matter what she eats. She went on an all organic diet for a few months, thinking that would make a difference, and she told me it didn't. Try the first 4 for a while before you change his food.
The first 4 things I've listed, she is very,very dilegent about. She has messed around with her diet, and it doesn't affect her break outs at all. The only time her eczema was totally cleared up is when she was pregnant, she was even cleared of it in the winter months when she was pregnant. She has thought of hormones being the problem, but she didn't want to mess around with hormone treatments to clear her eczyma-she didn't do well on birth control pills, they made her really cranky. Her eczyma has been so bad at times on her neck, that she looked like she had hickies, and then there would be times she would have very little rashes on her. Her neck, arms (inside middle part), and under her eyes, and the top of her wrists seem to be where she gets it the worst.
When her skin is cleared up, she doesn't seem to have scarring. She didn't when we were younger either.
Good Luck, be patient. It may clear up this summer. We have had an unusually dry, hard winter here in Western Washington.
