Good day doctor, I have been having this recurring headache and sensation. I have gone for a Brain CT Scan and everything is normal and yet the sensation and ache still comes and goes.although most times is not severe,but I m worried. And I also feel this dull pain at my lower left breast on the rib cage and sometimes leads to chest pain . I ve done an X-ray too and the result shows normality.pls what do I do.tnx
