My autistic 19 year old son occasionally has reddish stains in the front of his underwear that sometimes is very smelly, almost ammonia like. No sign of blood in pee and he says nothing hurts or seems to be abnormal. No history of anything that may explain this. What might this be?
Hello! Thank you for asking on Chat Doctor! The problems you describe seem to be related to a urinary tract infection. Although he doesn't complain about anything, you should consider the fact that his is autistic, and he may have an abnormal perception of pain. I would recommend performing a urinalysis and a urine bacterial culture. He may need to take antibiotics. Hope you will find this answer helpful! Kind regards,
