I am impressed. I am under a great deal of stress and not sure if my symptoms are stress related or something else. Basic symptoms: headaches, no appetite, chest pains, chills and absolutely no energy. I am 62 years old and am usually as active as a 20 year old; own my own business and am always feeling good. I thought about going to emergency yesterday, but decided it could be stress; even though I had pain in my shoulder that was listed as another sign of a heart attack. Trying to make it to 2017.
