i have a pain in my left breast , sometimes in the right. sometimes my ribs feel as if they have been punched. have seen several doctors, all the nasties ruled out, had endoscopy , ct scan and ultrasound, nothing found. i have lost weight as i am scared to eat, that is when the pain comes. i am taking 10 mg amitriptyline , (meant to be 20 but it wipes me out) but the pain comes through. i am 51 and healthy.
