My husband has been feeling really bad. It started Sunday after we had been out in the Sun on Saturday. He has had heat stroke in 2014. He tried to stay in shade but he was out side. He has had headaches, dizziness, back ache, nausea and indigestion. each symptom seems to come and go. He went to dr. yesterday and told doctor he thought he had a sinus infection. Dr. prescribed z pack and steroids. He has also had kidney stones in the past. He refused to have a ua yesterday, but I insisted he have one today, but they said it was not enough to test. He sometimes thinks he needs to go to hospital. His blood pressure runs 148/78 to 133//76 his pulse is around 60. He is diabetic but he is eating. He has not taken an accue test. Any ideas? Should he go to hospital?
