I have been going through some minor health issues, but being a hypochondriac, I just want to make sure it is nothing serious. My symptoms within the last few weeks have been mild tension headaches, eye strain, stomach upset, occasional fatigue, occasional muscle weakness, trouble focusing, and one day I had a pretty bad migraine (I never get migraines). Now, I have thought of possibilities for some of these symptoms, such as the fact that I might need new glasses and I stare at a computer screen all day for work. Also, I do not sleep well at all. But I have looked up symptoms of brain cancer and things like that, and I am worried I may have something very bad. I am just trying to make sure that I will be around to see my son grow up. Please help.
