As long as you still have an internal imbalance of sorts there will be external symptomology. Dont know what you have i'm not your homeopath. In homeopathy the entire person (physical,mental,emotional) is treated not only the skin ailment you called 'eczema'.................

The more suppression via allopathic meds the longer it takes to heal,i dont have an answer for you ,each patient heals at their own pace of course depending on the 'well chosen homeopathic remedy',if it's not the correct remedy nothing will happen.
