I'm in many ways a hypochondriac(when I hear of a symptom I automatically think that I have or have had it). And now that diseases have come to light and are a major apart of our generation its scary to think of what it could possibly be. I have some concerns about my health and just want to know if there are any answers that you can give to me. I have noticed lately that I have continuing yeast infections or discharge, I have lost weight and I headaches, which I've never had before. I also have had lack of growth in my toenails. I was wondering if there were any categories that these symptoms fit into?
