very sore on my left breast for the past 6mths. Visited my GP on several occassions. No lumps in any part of my breast or any kind of discharge. The breast feels heavy and tender when i'm not wearing a bra. I am on Pravitin 10mg for cholesterol since 1 week ago. Occasional sharp pain in my heart. Had ECG done 6weeks ago. Normal result. I am very wooried and dont know what to do.
