No you do not need to go to the physician for only 2 days of diarrhea. As long as you are able to keep fluids down you should begin to feel better in a day or so. Stick to a "low residue diet" such as chicken broth and rice. Also avoid drinking plain water, but rather something with electrolytes such as gatorade. If you need something to settle your stomach, natural gingerale or crystallized/dried ginger can help. They also make teas with ginger in them for this purpose.
This will pass and you are correct was most likely due to your meal.
Does that answer your question to satisfaction?
Feel better and nice talking with you! Feel free to contact me in the future if you need more help.
