The fact is NO BODY NEEDS a bra, male or female! The bra is really a personal choice article of clothing used for comfort and looks! There has been many medical articles published about the facts that there are really no medical reasons or benefits to wearing a bra, therefore it boils done to comfort and looks as I previously stated, and of course to control the bounce and dance under the tee shirt and black eyes from going up and down the steps for guys like me and aboywithgirls, lol.
As for why we get them? There are many reasons and many are side effects from medications. If that is how you got yours, you need to weight what is worse, the gynecomastia or what you would be dealing with if you were not taking the medications! There are many things in life that are worse then having some amount of breast on your chest.
Every time you get a new medication it would behoove you to do the research to find out exactly what kind of side effects of that medication has, don't depend on the doctor to tell or even know all of them.
It's always you right to take legal action if you feel you have been treated wrong medically, not that I agree with all these law suites you hear about on TV, but it is still your right!
Everyone should take control of yourown health care! When you don't understand something do research! This is where the internet is a blessing and ask questions or get 2nd or 3rd opioions. If you don't feel comfortable or feel something isn't right, move on until you do feel right about it!
It's you health, take charge of it, take care of it!
