Over the last month I have developed a tenderness around breats, under my arm, in my ribs and neck area and pain down my arm. I have been to the doctor twice. The first time they game me anti inflammatories and diagnosed mastitis. I have never had children or there is no possibility I'm pregnant. It subsided but a few days later the symptons returned and again I returned to my doctor, this time I was given antibiotics and anti inflammatories. I have been off work for this past week and taken my medication... but to no avail I still feel the same way and. Driving makes the symptons worse.
