thank you for your answer.
my doctor told me the same thing.
The symptoms you describe are relatively common, experienced by most people some of the time, including a variety of aches and pains, cough, dizziness and post-nasal drip. I have no doubt that you have experienced what you describe but it may well be that you “a person who worries too much” , may be attributing more significance to these symptoms than what is warranted.
The best advice I can give is that you convey all the symptoms, you have listed below, to your doctor, and let him pass judgment on the significance of each. From your description, he seems to be appropriately diligent and unlikely to miss any important or significant health problem. I would also suggest that you strive to focus less on your body and more on other things going on in your life.
Good luck
