Over the last month or so, I have heard of a number of people who had come down with the same slow progressing miserable cold virus that I suffered through (which I am almost finally done with, after three weeks). Today, my husband was at work and he realized that he really couldn't concentrate and was starting to feel extremely exhausted. So, he called our doctor and made an appointment. (I usually don't call the doctor unless there's something terribly acute going on, or if I've had something for a while that I can't shake or it seems to be getting worse.) He stopped home for a nap before his appointment and relayed his situation to me before I went off for my job interview.
When I got home from my interview, he was back in bed again. I asked him how his appointment went. Our doctor told him that he wants my husband to see a neurologist and to have a CAT scan.
I could understand if my husband had been having these symptoms for a week or more, or if he was displaying other profound neurological symptoms (loss of coordination, tingling, uneven pupils, etc.), but he's not displaying any such thing. I'm no doctor, but I would not be surprised in the least if he's just showing the early signs of coming down with the slow onset virus that I had. I spend about four days been REALLY tired before I had any other truly tangible symptoms.
So, my husband is going to see a neurologist for, what is more than likely, a cold!
