Hi, I am sorry you are going through all these issues.
The fact that when you are busy you do not notice the symptoms as much tells me that it is possibly anxiety related. That being said, if they continue or get worse, I would certainly see your PCP, he/she can then refer you to other physicians if needed.
Margypops is correct also, there are so many weird chemicals in our environment, one never knows what we are inhaling, eating, or drinking.
I have also been getting similar symptoms as you are and with no diagnosis , I have come to the conclusion its environmental allergies, It is a fact now that we are being sprayed with toxins, part of the government program of weatherisation..Take a look ot the utube video 'What on earth are they spraying' I have been like this for at least a year now and many others are also sick ..do some research, the video is 'worth watching
If you haven't seen a doctor then see one. Optometrist for your eye, and probably a neurologist to order immune disfunction testing and imaging studies. That's where I would start. Good luck and do t give up.
Oh yeah, AND...
blood pressure fluxuation
irregular pulse
chronically periodic sore throat
Thanks again.
