The likelihood of insurance covering your breast reduction surgery largely depends on the symptoms you experience due to symptomatic macromastia. Symptomatic macromastia is characterized by heavy breasts that can lead to various physical and emotional symptoms. Chronic Pain: Persistent pain in the neck, back, and shoulders due to the weight of the breasts. This pain can interfere with daily activities and significantly impact your quality of life. Skin Issues: Skin irritation and infections, particularly under the breast crease, due to moisture and friction. Grooving: Deep grooves on the shoulders from bra straps supporting the heavy breasts. Posture Problems: Poor posture and related complications due to the forward pull of the heavy breasts. Limited Physical Activity: Difficulty engaging in physical activities or exercise, leading to a sedentary lifestyle and related health issues. Nerve Pain: Tingling or numbness in the arms or fingers due to nerve compression. Emotional Distress: Emotional and psychological distress, including low self-esteem and social anxiety, stemming from the appearance and discomfort of large breasts. Given your symptoms of feeling heavy and sore 24/7, combined with the fact that you've wanted a reduction since your teenage years, it is evident that your condition significantly impacts your life. You should schedule a consultation with a plastic surgeon to discuss your options.
