Possible Recurring Tear??

So far this month my right inner labia/vestibule pain feels like a cut or tear. A few nights ago I think I actually felt the tear occur. It is deep in the fold of my inner labia, possibly my vestibule, and I can't actually see a tear. However, I used to get tears often back when I was still using those darn flushable wipes, and they were hard to see when they weren't buried deep in a fold; so just because I can't see it, I'm not ruling out that it may be there (plus I don't want to go digging so much that I hurt myself further).

Every month, a few days to a week before my period, this tear/pain happens in the same exact spot, and it won't go away until about a week and a half AFTER my period is over.

Has anyone ever had anything like this? Any advice would be great!

Could there be a connection between this tear and your hormones? It appears at the same time in your cycle.... I had tears like paper cuts last autumn, and they healed and did not return after i used local hormone-cream.

The pain does only seem to flare the week before, during, and after my period. I've been on a bioidentical estrogen suppository for about 2.5 months now (Estradiol 100mcg and Estrone 60mcg), but the only thing I've noticed is that my cycle has changed from averaging 30 days to now being closer to 34-35 (I still haven't gotten my period this month yet, but it's on its way). I'm not sure if the estrogen suppository is causing this, but I am completely fine with having a longer cycle

Prior to feeling like this was a tear, I had mentioned to my doctor that the pain seemed to go away for maybe 2 weeks out of a month, and he said the pain was due to the drop in estrogen before my period. I just find that so hard to wrap my head around because this tear/pain is so deep in my vestibule (deep in the space between my urethra and inner labia). I used to get tears all the time, and they would heal within about 3 days.

*sigh* I just wish I knew what was causing it...
