my 20 year old son has orange/red urine and stool, no appatite for two days, when ate vomited. He takes lithium for bipolor, and had high creatine levels almost two months ago and was told kidneys were shutting down, and then got better. Just moved to another state and doesn't have doctor yet. He doesn't want to go to emergency because of cost, so a doctors office during business hours would be best. Worried mom here, what can he do?
