Hubby came home from work at 5.30 and said he didnt feel well. He fell asleep on the sofa,no temp. Woke up bout 30 mins ago and went to the toilet. He did look a bit pale. I heard this altmighty thud and called his name with no answer. Ran upstairs and he had passed out hitting his head on the bath. His eyes were open but didnt respond for a couple of seconds. I put a cloth on his head and then he said he was going to be sick. Which he was...He says he hasnt got cramps on his tummy.Feeling a little better and doesnt seem to have a temp,yet. I dont know what to do. What could it be??? Please advise. Im so scared. He did say he felt a little nauseas at lunch and then started feeling flue not long after.
