Question: Fatigue and feeling "foggy or spacey"

 franklin1954 - Tue Dec 30, 2008 12:57 pm

I am a 54 year old male. For the past month or so I have had the following rather odd and vague symptoms which I have never experienced previously:

1. Feeling fatigued, even after a restful night's sleep.
2. Feeling continually "spacey" or "foggy" (like I would while taking with an
antihistimine, such as Benadryl. However I feel this without having taken such
a medication. Related to this, I sometimes feel "drunk" in my bodily
3. Feeling unusually hungry, especially early in the morning. (No, I'm not pregnant).
Note that food doesn't seem to lessen my fatigue or fogginess, either.
4. This sounds weird, but I occasionally go through fits of yawning, in which I
will literally repeadedly for several minutes if not longer, but yet I don't feel
especially sleepy or bored about anything.

Note that I recently visited my primary care phyician, who ordred some broad-spectrum blood tests, all of which came back negative. For instance, my blood sugar level was fine, and my thyroid was operating normally. In addition, I'm not experiencing any other symptoms other than the ones I listed above. My fear is that since these are rather vague symptoms, that might take doctors a very long time to come up with any concrete diagnosis. Any help would be greatly appreciated!

Thank you

User avatar Hi there -

Based on your description of your symptoms several things come to mind (but these are only the most prominent among many possibilities): MS should be ruled out, as this is often difficult to diagnose initially and can announce itself via this sort of symptomology; Chronic fatigue syndrome (CFS) needs to be explored, as it often also causes these same symptoms.

The hunger has to be given a pass, since blood sugar is normal. Yawning can sometimes be due to marked anemia due to GI bleeding (also ruled out by the blood work), but also can be due to hypercapnia, too much carbon dioxide in the blood, which is usually secondary to something else (often something as simple as inactivity -- in your case due to fatigue and lassitude).

There are other potential causes as well, but they become more remote and would take up too much space and time. You need to be evaluated first by a neurologist to rule out (at least initially) MS as well as idiopathic peripheral neuropathy, CFS and dysautonomia, among many potential causes. Blood work was appropriate, but it alone will clearly not explain anything further, having ruled out the most obvious causes already.

I hope this is helpful to you. Please follow up with us as needed. Good luck and do keep us updated.
