Tirepoet - you have mentioned having a full thyroid test, did it inclue T3, T4 and Thyroid Antibodies? You also mentioned TSH, ferretin, vitamin D etc and you say your doctor told you everything was normal. Sorry to say this, but due to my situation and a lot of other people's, i get skeptical when there is obviously something wrong, yet doctors look at your test results and say you are 'normal', 'all ok', 'all within range'. To me these days that is garbage and that is due to me spending 8 whole years trying to work out why i was losing hair. I had an Endo in 2001 tell me my thyroid was normal, yet even then i had Hashimoto's. It wasn't until i went to see a Trichologist just over a year ago for my hair shedding that he was suspicious of my thyroid and ran tests and i had high thyroid antibodies and my T4 and T3 were low, my TSH was about 2.50. I was tired all the time, lived in a type of brain fog, felt like i'd been hit by a bus, my ferretin kept dropping even though i ate red meat and was difficult to raise, my vitamin D was low, iodine was low, basically i was one big mess.
My Trichologist was wonderful and helped me as much as he could, then after finding out about the Hashimoto's he passed me onto another great doctor who has been treating my thyroid and other things they have uncovered.
He has done a full hormone test using a saliva panel test as this is more accurate than a blood test. My testosterone was a bit high, i have excess estrogen and the cortisol for my adrenal glands was too low. Low cortisol alone will give you excess tiredness and brain fog. Once i began meds to boost my cortisol i've never looked back.
Your acne and facial hairs could all be hormonal. The pill is often a bandaide fix for things which are going wrong. I know back in 2001 my gp tried to put me on the pill and i tried 3 different brands which all gave me extreme side effects. The pill isn't for everybody and you need to be on the right type of pill for you. Just because one brand works brilliantly for your friend, it wont necessarily work well for you.
If you have your thyroid and ferretin results you ought to post them. Depending on how your lab does the results i might be able to read them as different countries use different ranges. If someone on here can't read them then you ought to post them over on the thyroid board. With ferretin, a lot of doctors say 'normal' when you should actually be higher. Ferretin for correct hair cycle growth ought to be 70 or over. You can find out more on the anemia board.
A lot of women will have some dark hairs at their jaw, chin or upper lip. They are easily removed for good with electrolysis. It can be due to genetic or hormonal reasons, either way electrolysis is fantastic for that type of thing.
With acne, i have read articles from doctors who have stated its due to a hormonal imbalance. It's a good idea to go off the pill for a short time, just so you can have a hormonal test done and not have the effects of the pill skew your results.
Always make certain you obtain copies of all your test results. If you aren't sure about certain tests and what time of day to have them, what type of tests are better than others eg; blood/urine/saliva, simply post on the relevant section of the board and someone will help out due to them already experiencing that. If a doctor passes you of as being normal, you can always confirm test results on the relevant section of the healthboard. I wish i'd known about these boards when i first began looking for answers.
Hoping you get to the bottome of your problems soon and it doesn't take 8 years like mine did
