Needle-like stabbing pain in the chest is considered to be a symptom of breast enlargement. The needle-like stabbing pain appears before the menstrual cycle and can be significantly relieved after the onset of menstruation, which is caused by the imbalance of estrogen and progesterone hormones in women’s bodies. When you are angry or under stress, you may also experience chest pains. If the symptoms are obvious, you can have an ultrasound examination to confirm the diagnosis and provide timely symptomatic medication. If the pain is not relieved, you need to follow up regularly, and if necessary, further confirm the diagnosis to exclude malignant tumor. Pain in the chest can also be due to soft tissue injury caused by extrusion and impact trauma, which does not require treatment and can be relieved quickly, with local heat application in severe cases.
