My son age 32 has self diagnosed himself with post acute withdrawal syndrome through looking at online symptom checker sites. He did drink and binge drink but not more than most young,single people and does not consider himself to be an alcoholic and does not miss alcohol after quitting 5 weeks ago. He never experienced any alcohol withdrawal symptoms. Is it possible that he can have post acute withdrawal symptom? He has been to several doctors at university hospitals and no one can diagnose his problem. So he has self diagnosed. His symptoms are confusion, lack of energy, memory loss, occasion hot sweats, lack of concentration, periods of vertigo. All of this starting immediately after having one episode of a seizure while drinking 2 years ago. No more seizures since. Second question. Could any of this be the result of some thing he may have contracted during months of traveling in Brazil and Southeast Asia? Perhaps something the CDC might be aware of? Thank you for your service.
