You do have lots going and like you I had a difficult time getting a diagnosis. Grover's isn't suppose to run in families, yet my sister has it also. It is possible to have multiple types of eczema, I do. You mention rash on elbows and legs but I am wondering if that is a different form of eczema than GD. Typically GD doesn't manifest in those areas. Have you been tested for Allergic Contact Dermatitis, ACD? Look up 5 Day Extended Patch Test. Very few of us get relief from steroids with GD. I never did, yet they would help with my one of my other forms of eczema, ACD is helped by steroids when symptomatic. What is MCTD? What you need to do is to go back to Feb or March of 2019 in this blog because it really is a long story to retell. Kimass1 is the blogger who brought it to our attention. You can follow our personal successes and failures trying cilantro. We are stumbling and just guessing on how much to use because there is so little info about this herbal treatment. My derms never heard of it. We share our recipes, how much cilantro we use, how to keep it fresh longer in the refrigerator and how to freeze. We share when we start to notice improvement and how long it takes to be certain we are in remission. Also even in remission many of us have scabs which no longer itch, but simply don't fall off for months. I think it took a full year for every single scab to drop off. None of us had success with cilantro tablets.
