Alright so this has been plaguing me for about 2.5-3 weeks maybe. When I lay down, I'll usually recline my head against a pillow and look at my laptop or the tv. Occasionally while doing this, I'll have dizzy spells and suddenly feel nauseated. It sometimes coincides with the stimuli on the screen as well which may or may not be causing these feelings. Almost like sensory overload. It began shortly before having to give a speech to a business call of about 40 people. It was way out of my comfort zone and I was so nervous I drove myself sick. That's when I started noticing the dizzy spells and also some weird pressure at the base of my occipital bone (back of head) as well as across my forehead where the brow line is.
The dizzy spells usually can occur with or without this cranial pressure sensation, but I would say I normally have both occurring simultaneously. The feeling of being dizzy normally lapses in about a second or two and typically goes away if I adjust my posture or sit/stand up. The pressure on my forehead also impacts my vision. Sometimes I'll find it hard to concentrate on something on the screen almost like a migraine, but it normally has that band around the head sensation when I do, and I find it really occurs during the times after I've eaten a meal and laid down. Now, I did some looking online and dizziness and headache, or pressure in my case pointed to a tension headache which can be brought on by stress and anxiety... right? Bingo. Must be that, but for three weeks, and so intermittently? I get that maybe I stressed out a neck muscle or something, but I wouldn't say there's like a throbbing neck ache or anything to go along with this ordeal. It feels kind of stiff right now and if I shake my head from left to right, I feel like my body is apprehensive in doing so, and I also can simulate or cause that feeling of dizziness when I do...
Now for the record, I'm 35, 230-235lbs and decently in shape, was working out routinely at a gym before CV. I was taking a multivitamin before this occurred and had been for around a year before this happened. Literally ran out a few days before hand. I'm also on a grain and a quarter of NP Thyroid meds for hashimoto's thyroiditis. My thoughts are that my thyroid could be the culprit and I need to check my dosage too, but while both my feet and hands get cold at times, there's no real other symptoms of low thyroid, so I'm a bit confused and also getting a bit anxious. I don't want this feeling to be a thing forever. I've attached a picture of where the aches or pressure present themselves on my head and neck below. There's also an acute pain above my right eye at times, and some gastrointestinal discomfort on occasion but they're infrequent. For a while I was thinking I had a fever or some kind of sinus infection due to the feeling of being almost in a woozy drunken state and dizzy. It has kind of gotten better over the past few weeks, and sometimes isn't a problem much if at all on certain days. Aside from icing my neck and getting my thyroid levels checked, I don't really know where else to turn. For the record, taking a allergy pill kind of helped out a little, and so did adding an extra dose of my thyroid meds on the same day. Not 100% better... but better.
Alfuzosin dose spread out through the day or all at once.
