A bout of tingling breast pain may be due to premenstrual syndrome, or mastitis, breast cancer and other diseases. 1. Premenstrual syndrome: Research has shown that it may be related to ovarian hormone imbalance and neurotransmitter abnormalities, and common triggering factors include emotional stress, anxiety, and social environment. Women often experience breast pain and limb edema before the onset of menstruation, and the pain can be manifested as tingling or swelling. 2. Mastitis: In the case of breastfeeding mastitis, common causes include milk stasis and bacterial infection. If it’s a non-lactating mastitis, it may be related to smoking, nipple inversion, breast trauma, drug stimulation, autoimmune factors and so on. Although there is variability in clinical manifestations, most patients experience breast pain and elevated skin temperature. 3. Breast cancer: the cause of this disease is not yet clear, and it may be related to factors such as radiation treatment of the chest, heredity, gene mutation, improper diet, excessive alcohol consumption and so on. Symptoms are not obvious in the early stage. With further development of the disease, most patients will have painless lumps, but some patients will have stabbing pain and hidden pain, which is manifested as a burst of breast pain. There are many causes of breast pain, such as breast hyperplasia and other factors, and it is necessary to go to the hospital to clarify the cause of the disease.
