Rt headache & chest pain. To you?

Last morning after the yoga classes my mom had severe Right occipital headache radiating to the frontal lobe and severe chest pain which presented as a pulling type of pain. This kheechaav(pulling) type of pain radiated to her right arm and right leg, she was immediately admited to the hospital nearby, started her on Piracetam i.v the doc ordered a limited plate brain MRI, but MRI report was absolutely normal. she had been early been diagnosed as having MIGRAINE in 2003 and 2014 but now the medications are not working, in 2011 she had undergone cholecystectomy. NO history of HTN or DM or TRAUMA. have seen to a neurologist today but doc told her that she's having some stress and she started her on antianxiety drugs and told that she's having SOMATOFORM DISORDER which i dont found to be satisfactory, she rejected her of having migraine. PLEASE I REQUEST YOU TO KINDLY PROVIDE A SATISFACTORY DIAGNOSIS INTO THIS MATTER, .I SHALL REMAIN THANKFUL TO YOU
