Fibroids can cause pain in the small abdomen because when fibroids grow on the uterus, the uterus becomes larger and stimulates the uterus to contract, causing occasional vague pain or swelling. In the case of large fibroids, some fibroids may become red and the pain in the lower abdomen may become more severe, and if necessary, anti-inflammatory drugs may be needed to relieve the pain. If the fibroids are larger than 5 cm and cause frequent pain or prolonged menstrual periods, increased menstrual flow, or even anemia, or if some people have symptoms of pressure, such as frequent urination or constipation, which affect their daily work and life, they need to be removed surgically to relieve the pain.
