Dizzy and brain fog?

[calguy]

Ok well thought I would throw this out here cause at a loss and docs arent much help yet.

About 2 weeks I ended up in ER for dehydration and ever since then I have been dizzy and in a fog. Almost feels like my body is fight something. Thought it might be sinus infection but no sign of infection. ENT said my nasal passages could be inflamed due to allergies but never had problem with allergies. He put me antihistamine spray and prescription claretin. These have helped and feel better and 2 days but the scary thing is when I push my body I get dizzy. Walking on treadmill with any kind of intensity makes me dizzy. Blood work ok, blood pressure fine and blood sugar ok to. I had this before when chronic prostatitis / chronic pelvic pain syndrome first hit me and that was due to anxiety and stress and believe I just burned my adrenal glands out, but was never dizzy. Have been having slight neck and jaw problems which is slight case of tmj. Headaches, dizzy, head fog and kinda lazy. Like I said this all started after dehydration incident. Could my body just need time to adjust? Getting more test done next couple weeks so will see but any ideas welcome? Never knew antihistamine are prescribed to help dizziness either.

I'm not a MD, but I'd be suspicious of either kidney (kidney failure) or circulation (embolism) problems if this is related to the dehydration incident. Dehydration makes it easier for blood clots to form. Those are the most serious possible causes, but there are probably many more less serious things that could be going on.
