Symptoms of mastitis in men are breast lumps, swelling and pain, which need to be treated with medication and surgery so as to improve the symptoms of the disease. The cause of mastitis is not clear, but may be due to autoimmune deficiencies, bacterial infections, trauma to the breast, or drug stimulation. Symptoms of mastitis in men and women are basically similar and may include breast lumps, nipple inversion, breast pain, redness of the skin, and increased skin temperature. As the disease progresses, the lump can form an abscess, and the abscess breaks down to form a breast fistula. If the patient has a local inflammatory reaction, you can take oral antibiotic drugs under the guidance of the doctor, such as levofloxacin and other quinolone antibiotics. Or take surgical treatment, such as lumpectomy, abscess aspiration, mastectomy and so on. Most patients can control the development of the disease after relevant treatment measures, thus relieving the symptoms of the disease and improving the prognosis. Once a man is diagnosed with mastitis, he should actively cooperate with the doctor to take relevant treatment measures to avoid delaying his condition. At the same time, keep an optimistic and positive mindset, do not generate negative emotions.
