To all of you ladies out there who think they are going crazy---your not. I had a hysterectomy immediately after the birth of my son in 1994. I have one ovary. About 4 years ago, my head hair, arm hair and leg hair fell out. Was diagnosed with underactive thyroid and put on Synthroid. My wonderful female doctor also tested me f for everthing from lupus to rhuemetoid arthritis and hormones. At that time,everthing was normal. Since that, I'v had a lymph node removed and biopsied, and a pollup removed in a colonoscopy. The last year or so, have been having heart palpitations, stomach inconveniences, and now my left eyebrow is falling out. My hair on my head never did grow back. These "attacks" come only at night every 3 or 3-1/2 weeks. At first, heart attack was my first thought. Have had EKG's, and worn an "event heart monitor". As of right now, I am due for some more blood work, hepatitis C, sed rate, anti nuclear, and I insisted on a hormone check. I believe it does have something to do with peri/pre menapause. What I want to say is just be persistent with your doctor. Keep a journal of times/symtoms. And if your doctor won't listen, find one who will. Educate yourself. It's your body and nobody knows it better than you. If you think something is not right, then it's probably not. God blessed us with the ability to bear children, now we have to deal with the wrath our bodies are bearing on us. Good health to everyone and HANG IN THERE.
