Hi Yammy1
I had a similar result when I first started HRT. Had my ovaries removed and was sat at home, recovering, with nothing else to do but to pick the spots! In actual fact, they were more like boils than spots, as there was no "head" to them. Sorry if TMI!!!
I found reducing the dosage of my HRT helped, although I actually moved to a different HRT (lower dosage) so not sure whether it was the lower dose or different HRT that did the trick.
