Read all about fibroid pain here and find out how to treat fibroid symptoms. Uterine fibroids are usually painless and do not normally cause symptoms, but this is not much consolation if your fibroids are painful. A fibroid is only painful for a reason. If one grows large enough then it can produce pelvic discomfort simply because of its size. A large fibroid will stretch uterine ligaments and press on other pelvic organs within the pelvis. Bodily movements and even simply walking around may cause a fibroid to produce pelvic pain if it is above a certain size.
