My son worked out and afterwards went jogging at the park that night he developed nausea, his left arm was hurting, he was dizzy, couldn t sleep. Went to the clinic they told him his hemoglobin was high. He has been drinking a lot of fluids, now three days later he did one hour of workout and symptoms return. He needs to teach Zumba tomorrow and he doesn t know what to do, what is the treatment?
