I moved to Japan about a month ago and since I've arrived I've been experiencing persistent and intense stomach problems. I can't yet go to the doctor because my health card hasn't arrived yet. I have been eating pretty well, still including fiber in my diet and plenty of water. However, my stomach is in shambles. I have aches, pains, and I am feeling highly fatigued and dizzy a lot of the time. I have to eliminate a couple times a day, and it's always a painful experience. I'm getting muscle weakness, a sore throat, and nausea pretty frequently. My food doesn't seem to be digesting properly and it's not solid. I'm starting to get kind of worried...does anyone know what might be going on and how I can fix it?
