My son (32 yrs) has been in Dubai UAE for the past three months but prior to that he was in India for three months. He has ear & throat infection & has had diarrhea for the previous two weeks. He has ongoing stomach upsets for the past two months with constant fatigue. His heartbeat is 120 for the past two days with temperature of 40C. He is taking antibiotics by intravenius (can not swallow as throat is swollen) but no diognosis as of yet. Any suggestion as to what might be the problem? Also could there be any connection between the ear/throat infection and the diarrhea?

Thank you.
