I am 18 and have had episodes in my life in which I feel anxiety about my health. I am a very anxious person about situations that I am facing. Currently, I am about to start college and have had consistent nausea/headaches and stomach aches during the past 2 1/2 weeks. About 3 years ago I had the same symptoms and went to a neurologist and gastrointestinal specialist because I was scared that something serious was going on. All the test came back negative and I started feeling better after leaving the doctors office. I believe this is the same situation again. I have also started a exercise regimen this month and started consuming whey protein (60 gram shakes) to build muscles.
