My husband started experiencing weird symptoms over a week ago we went to er after he was sent home from a very stressful job due to not being able to communicate with employer he was not making sense when he was talking.. The ER doc said that his blood sugar was 160 and that he was overworked and needed sleep he was still having symptoms which were getting worse he experienced delusions at the ER and continued we followed up with our Primary care physician who ordered more blood work and a MRI . He is also on his Fifth day today of withdrawing off of Percocet and opana er. My questions are why is he still delusional and is this normal. We r waiting for the results of the tests but we r going through extreme symptoms and r very worried please help....
