My headache always come on when I do any physical activity. I am trying to get back into shape, as I also suffer from anxiety. For example I was just at Lowes yesterday and was lifting a 40lb bag of bird seed and bringing it out to my car and here come the light headedness/ headache. I know I am not that out of shape. I also have constant ringing in my ears. I have had CT scans and MRI's and they were all ok. My DR. has started me on topamax. Does anyone else have this problem???
