There is lots of research showing that HRT protects women against cancers, osteoporosis and heart disease (bio-identical HRT that is). I would not touch the chemical form the docs give. I can't believe they are still handing those things out after all the bad research showing they can cause cancers.
Itchy skin is one of like 66 symptoms listed online for meno/peri. My skin itches too.
Funny, in a few weeks, I also will be one year without a period, which is officially menopause.
Have you had your FSH levels checked? A high level diagnoses it also.
I however, want my period back (crazy, right), and am hoping mine is missing because my estrogen levels are low, but I am thin and don't have a lot of body fat. I also confirmed it with a saliva hormone test.
I wish I'd known progesterone is the first one to drop, not estrogen. Often times, just using bio-identical progesterone, which you can get from health food stores, will fix many symptoms.
As far as HRT, you can take chemically-altered hormones your docs hand out (would not recommend it), or bio-identical creams available as mentioned (there are also ones for estrogen), or find a practitioner that will prescribe bio-identical creams through a compounding pharmacy (usually all out of pocket).
There are also estrogen patches (some bio, some not) and testosterone shots.
Some docs require a blood test (most MDs or Gyns don't believe in saliva tests, only blood testing) before writing scripts, others go by symptoms because hormones fluctuate at this time of our lives.
DIM is also a great supplement for balancing estrogen levels and clearing the bad ones from your system.
Looks like you are taking good supplements. Be sure to take B vitamins also...great for mood, energy, nervous system, and zinc. Both are necessary for hormone synthesis.
I hope this helps!
