Hi! I had my FSH level done in January, which was when it was "9" I think. I know it showed "non-menopausal" levels. I was wondering if anyone had any experience with having a normal (meaning non-menopausal in this case) level and then later an elevated level. I wondered about how quickly that could happen. (Go from non-menopausal to menopausal levels of FSH) I started taking the celebrex on July 17th and noticed the hot flashes probably the end of that month (not mid August as I posted earlier). They could have been occurring before then, I'm not sure, we've had a very hot summer so I may not have noticed. When I did notice them, I thought of the drug and checked the side effects, and sure enough, hot flushes are one of them, but not one of the most common. They are not listed as a side effect of celebrex on the website that Helen provided. But I have been off celebrex for 12 days now and the hot flashes continue at the same intensity. I have no idea where in my cycle I am because I had a hysterectomy. This is the problem. The FSH test is the only thing I have to determine the need for estrogen replacement. I'm not sure that they will treat you for hot flashes (with estrogen) if the FSH does not show menopausal levels.
