Recently (I would guess about 3-4 days now) I have been feeling slightly lightheaded, almost as if I had a head cold, where my head feels kind of foggy. However this does not affect my vision, nor does it affect my thinking (I can talk fine, think fine, I play my puzzle games without a hitch). But it just seems like I'm .. dizzy inside my head. It used to happen only around 10pm at night, however recently it's just.. a constant thing. Every so often my right arm will get tingly (not enough to be totally numb, but enough to be noticeable). It may be unrelated but I've also noticed that I've become more gassy than usual and stress/anxiety tends to enhance the symptoms. I've checked my blood pressure and it was 107/67 and my heart rate is usually 88 BPM. I'm been wracking my head for the past few days trying to figure out possible causes (from maybe a pinched nerve in my back to me just making all of this up with my GAD! I can't get checked until I get paid, so any help in the meantime would be most appreciated.
