After eating, there is a dull pain just below the left breast.

There are several possible reasons for dull pain below the left breast after eating, with common causes including improper diet, costochondritis, myocarditis, mammary hyperplasia, and gastric ulcer. Appropriate management methods can be selected based on the specific cause.

1. Improper Diet

Overeating or eating too quickly frequently may lead to stomach bloating or acid reflux, causing dull pain below the left breast after meals. Abdominal massage may help, and maintaining healthy eating habits is recommended.

2. Costochondritis

Inflammation may cause pain in the cartilage connecting the ribs and sternum. Chest muscle movement during eating can pull on the affected area, resulting in the aforementioned pain, possibly accompanied by symptoms such as coughing. Follow medical advice to use medications such as ibuprofen capsules, naproxen sustained-release tablets, or indomethacin capsules for treatment.

3. Myocarditis

Inflammatory reactions in the heart muscle can cause chest pain that may radiate to the breast area. Pain may worsen after eating, leading to the symptoms described, possibly accompanied by palpitations or diarrhea. Follow medical guidance to use anti-infective medications such as metronidazole tablets, acyclovir tablets, or valacyclovir hydrochloride tablets.

4. Mammary Hyperplasia

Abnormal proliferation of breast tissue can cause pain and discomfort in the breast area. Abdominal muscle movement during eating may exert pressure on the breasts, increasing local pain and causing the aforementioned symptoms, possibly accompanied by breast lumps. Under medical supervision, anti-estrogen medications such as cyproterone acetate tablets, medroxyprogesterone acetate tablets, or megestrol acetate dispersible tablets may be prescribed.

5. Gastric Ulcer

Eating can irritate the ulcerated areas in the stomach, causing pain that may radiate to the chest, resulting in the described discomfort, possibly accompanied by a burning sensation in the chest. Under medical guidance, acid-suppressing medications such as omeprazole enteric-coated capsules, lansoprazole enteric-coated tablets, or rabeprazole sodium enteric-coated tablets may be used to relieve symptoms.

Patients are advised to seek timely medical evaluation for accurate diagnosis and appropriate treatment under professional medical supervision.
