I see this frequently in my child patients. It often starts after the first round of vaccinations. Then it is suppressed with steroids and usually disappears and asthma appears. If this is successfully suppressed with steroids further we usually see mental health problems & some severe behaviour problems. Here's a case study illustration of what I'm seeing frequently and why I think it happens. http://sallylloydhomeopathy.com/got-sick-get-well/
During homeopathic treatment we have to move back through the asthma [mental health and behaviour improve, asthma returns], resolve the asthma to the point where the parent can safely withdraw the steroid meds [this is the parent and doctor's business, not mine], then as the asthma gets better the eczema resurfaces. It's a lengthy battle sometimes to get through the asthma stage because steroids antidote homeopathy. It is very doable though. I've taken many patients through this stage. However, the most difficult stage for parents and children is getting through the eczema without returning to steroid creams. The case I describe above has been right back to the beginning once because of slapping on the hydrocortisone. It took another 8 months to get back to where we had been. His eczema was not a particularly severe case, but different people have different levels of patience and tolerance. Some of the eczema cases I've treated had VERY severe eczema and we've had to work with some steroid cream gradually diluted out with base cream until it improves enough to manage without. Then detoxing the steroids will often finish the treatment and leave the child clear of eczema. It is SO much easier to treat the eczema than to meet the child a few years down the line with full blown anxiety, autism or psychosis.
