Hi Jane,
Hopefully this news will cheer the life outta-ya. For the past 40+ years I've had, mild by comparison, Psoriasis. Typically groin (very bad) underarms, elbow joints, head and chest. I say mild, because I've seen much worse.
It was to a point, particularly the groin area, like ground zero for vaginaoplasty, it wasn't looking good. Even had the skin specialist booked. My Endo gave me an early Christmas present and prescribed Estradoil 100 while waiting for bloods to come back and see what he would do about blockers.
Week 3 into the patch, elbows cleared. Week 4 head/chest cleared, groin improved substantially. Week 5 all cleared, except for groin, which is profoundly improved. On my last visit to Endo, told him I was over the moon for all the wrong reasons. He commented that Estrogen can do this sometimes.
As my understanding that eczema is a lesser version of Psoriasis, hopefully HRT will improve your condition. I say this in the light of literally throwing everything at my 'P' with little to no effect over the time. It just had a mind of its own. Maybe it's the 'Universe' speaking, "You should have done this YEARS ago"
Sincerely hope it works for you.
Be safe, well and happy
Lotsa huggs
Catherine
