I haven't updated in a bit mostly because I found a regimen that is working for me and I've had slow but steady progress.
However, the other day, I first noticed that I have developed gynecomastia on my right nipple (only the right, not the left). To anyone wondering out there whether they have gynecomastia or if they're just imagining things: you'll know it if you got it. My nipple is very tender and there is a small coin-sized hard lump directly below my nipple where the mammary gland is developing. Again, I only have this on my right nipple, not the left.
I find it strange that I'm developing gyno now 3 months into my current regimen and 6 months after starting any treatment. Changes I've made recently:
* Increased topical estriol application from ~40mg/day (what Pegasus reccomended on his thread) to ~60mg/day
* added topical betamethasone once/day
* started using more aggressive microneedling with one of those electronic devices
now the microneedling by itself can't cause gyno, but it could cause more absorption of other compounds. If it's true that betamethasone causes an upregulation of aromatase, that could theoretically cause gyno too, but I'm not sure if just using it on my scalp once a day would actually have a considerable effect. Obviously the estriol could be causing it.
It could also be the dutasteride I've been taking, since gyno is a possible side effect of that. However, I've been on dutasteride and previously finasteride for a while so I'm not sure why I'd develop gyno just now
I'm going to stop using estriol and betamethasone for a little while. I'm hoping the gyno will go away by itself in 1 to 2 weeks then I'll try reintroducing estriol at a lower dose.
Anyone have thoughts on my situation?
