Hello. I have reviewed your query and here is my advice. With the help of articles and pictures, do not diagnose yourself and decide yourself. Because such a diagnosis will ruin yourself, rob you off from mental peace and you will be stressed and depressed. The first question I wish to ask you is, have you tried chest muscle tightening rigorous physical exercises for continuously 3 months? If no, please do it. Gynecomastia is an enlargement or swelling of breast tissue in males. It is most commonly caused by male estrogen levels that are too high or are out of balance with testosterone levels. Treatment may not be required in some cases. In other cases, treatment focuses on managing the underlying condition. Rarely, medical or surgical treatment is necessary. Hope I have answered your query. You can contact me for treatment options. Let me know if I can assist you further. Regards, Dr. K. V. Anand
