[ English > Japanese ] Translation to be used as a medical note in case of emergency.

I will be traveling to Japan on the first of the year and I have just gotten a splenectomy 12/1/17. I am cleared with my Doctors for the travel but if i get a fever over 101F I must go to the hospital immediately. I would love some help with some translation for a note i can use just in case the people in the hospital cant understand me. I would like the note to say something along the lines of:

I had surgery on 12/1/17 for the removal of my spleen do to a blood disorder. My doctor has stated that if i were to get a fever over 101F I must go to the hospital.
