Guest, Fibroids are benign tumours, that for reasons known only to themselves, grow in (mostly) the uterus. Most women have them by their forties. They can be singular or multiple. They can stay small and cause NO problems or they can grow and grow and cause a HUMUNGOUS array of health problems, from annoying to downright painful and dangerous. In the US, a large percentage of diagnosed fibroids end in unnecessary hysterectomies - but that's another story!! If you think there's a chance you have these (putting on weight, e.g.), checkout this site : http://www.uterinefibroids.com (but be warned, it can be unsettling reading) Speaking from personal experience, I sincerely hope your symptoms are NOT caused by fibroids.
