Hi, so I ve had quite a few symptoms in the past month or so. A few weeks back I had went to the doctor for shortness of breath, I would have trouble falling asleep, and would feel like my throat was closing up. One night I had heartburn along with the normal symptom. It would happen in class as well on occasion. The doctor believed I was having acid reflux, giving me sort of asthmatic symptoms, and gave me Nexium plus advised me to hydrate myself better. This seemed to fix the problem... mostly. Over the weeks I was taking Nexium, I quit taking Plexus supplements and creatine. Two days ago and tonight I experienced a weird feeling of lightheadedness, nausea, and felt like the room heated up (sort of felt clammy, sweaty hands). I never threw up but the symptoms were very bothering and scary to me. (Also a student nurse checked my blood pressure a few hours after my first episode and commented that it was slightly lower than average but I don t recall the numbers. Plus I have been checked out for diabetes and did not get results showing I did have it.)
