That is good news to have a diagnoses. When my rash started, and I was reading possible causes, it said Thyroid. I organised a blood test, and afterward heard nothing which I took to mean it was ok. I have just got three patches re-occur on my right wrist, and it followed immediately after cutting back the Lobelia. I though about Lobelia the first time, because it co-incided and I noticed latex bleeding from them.
The Doc made an urgent appointment for me to see the dermatologist, ha ha, still waiting.
It is so much better when you are able to find a cause and I feel certain that once you get the correct dosage you will feel so much better as well. Good luck, Mrs Bouquet
