I am sorry to hear that you have been feeling these symptoms for almost an entire month.
There can be many different causes of soreness in your breasts. The cause will also then depend on many different factors in your life such as whether you are breast feeding, on any hormonal medications etc.
My advice is for you to consult an experienced women's health doctor regarding your problem as you have been experiencing such symptoms for almost one month without resolution.
Your doctor will then be able to examine you and may order further investigations such as a breast ultrasound if required.
Hope this addresses your worries!
Regards,
Dr Michelle Chia
