Synthroid and pimples

I have just been switched to Synthroid (by my Endocrinologist) after being on Armour for 4 years. I have to tell all you out there that think "Armour" is the save all drug..and believe me I am not an advocate of Synthroid either because I have not been on it long enough to know what possible side effects I might have..however when I first started on Armour I felt like I did before I had been diagnosed with Hypothyroidism ..then about 1 yr ago I started to gain rate rapidly like 40lbs in 6 months feeling sluggish, off and on skin problems, puffy hands, face, feet,hives, pimples in the back of my head almost hive like,some hair loss that is noticeable to me as I have had very thick curly hair all my life now it is getting noticeably thin and It is making me very nervous...My Endo put me on .75 mcg Synthroid and .5mcg Cytomel which she calls a "controlled Armour"..Armour does not stay consistent with your T4's and T3 levels and that is what cause my thyroid to become suppressed and these are the symptoms I was experiencing...she also put me on Spironolactone which is a mild diuretic to lose the puffiness in my face,hands,and feet and so far so good...Like I stated earlier, I am not an advocate of Synthroid or Armour our any drug for that matter, I just want to find what is right for me and stick with it..and if Synthroid doesn't work for me, then I will try something else...Just remember one very important thing.."You" are the only one who knows how you feel and Dr's are not God they can't fix everyone that is why its very important to read about your disease and find out what things might work for you..I suggest getting this book I bought that was recommended to me by my Endocrinologist called "Screaming to be Heard" Hormone connections women suspect and doctors still ignore written by Elizabeth Lee Vliet, MD...its a fabulous book and I am sure all you women can relate to this book...its all about us....Most important thing is to stay healthy eat a well balance diet and exercise..also find out about the foods that only worsen thyroid problems...
