What is your FREE T3 and FREE T4? Those are more important than TSH. And my TSH is 2.8 but I want it lower and will be asking my dr to up my medication next month.
YES. The week before I start my period is my huge PMS week, and EVERYTHING is WORSE. All my symptoms are worse that time of month, including other things besides my pn.
Yes, take supplements. Go to the sticky at the top of this page and read the supplements page, then ask questions after you read. My MUST haves are benfotiamine, magnesium, potassium, B12. There are others but those are my never live without.
Epsom salt baths are VERY HELPFUL. I take them all the time, epsom salt is magnesium and it gets into the blood stream faster when in a hot bath. LOVE THEM. Lowers blood pressure, helps sore aching muscles and helps my feet pain and burning.
I have lost 40 pounds through this because I have cut out the carbs. Carbs make my pn worse. I also wont allow my BG to get above 140 so I keep my carbs around 30g a day. There are others here, like Sally, she does not have diabetes but eats low carb for same reasons. Many say carbs make pn worse.
I exercise even though my feet burn when I am done. Walking is worse so I do arobics. When I take my shoes off my toes are red and on fire but I do it anyway.
I understand your fear. Fear can immobilize us. Worse thing to fear, is fear itself, so confront the fear by being in control. Read, research and keep faith. It IS good to talk to others, that is why I stay here.

I also find so much help here.
