I have allergy related issues like stuffy nose, head ache, irritation or dryness of the eyes. I have acidity and gastric issues too. I sometimes feel that both are related. On and for certain things, I find myself having anxiety. For eg: when it comes to health, whether it is of children wife or myself. I get into an anxiety when measuring BP. Or sometimes on a special meeting with someone. I feel shivering of my body or may be voice. How effective is homeopathy on this?
