                        Is it possible to be allergic to medicines such as benedryl or high blood pressure medication?  I know it sounds crazy, but someone had told me I may not be allergic to the medicine itself, but the ingredients used to make the medicine.  Please help.  Also, can you be allergic to a food or aeresol spray without a rash or face blowing up, etc.  You just feel bad.
