Husband having TIA symptoms and has had a work up but nothing shows up. Sometime light symptoms such as numbness in lip/tongue, left pointer finger goes numb, other times much more severe with added dizzyness, so he almost falls, left arm heavy plus the above problems added.. All we are told is if they don t get worse, just rest. They added plavix and statin drug even when his numbers are not high. What else can we do?
