Wow, you are very fortunate that you could find some answers. I've had my hormones tested for years. I even spent $200 for saliva hormone testing to find everything within "normal" ranges.
Let me know if you find out anything else!
ALSO my doctor told me that losing Calcium can ALSO give this side effect. So maybe you have low calcium and just need a simple supplement. Hope you get some answers.
I have had the same thing for years. I mean I sweat in the winter and I'm in Colorado in the mountains, so we get some serious snow, and I was SWEATING in the SNOW!! I was diagnosed with endometriosis last year after not being able to conceive and cysts constantly rupturing on my ovary (extremely painful, might I add). They said that the endometriosis most likely caused my hormones to become unbalanced cause my "HOLY CRAP I'M ON FIRE FROM THE INSIDE" symptoms. Unfortunately, I've been on treatment for the endometriosis which induced me into menopause and caused Hot flashes that felt like they are powered straight from hell's flames. BUT they said that ALL this treatment should make me feel normal again.
For you, it could be a hormone imbalance. Just talk to your doctor and see what they want to do. It's just a simple blood test to see if your hormones are off. If they are normal, then they may try something else. Good luck.
