My head feels like there is pressure, not congested, no cold, no allergies. Not really dizzy or lightheaded. Been going on for months. Back of legs feel weak also from time to time. Not really wobbly but feel like I should be. Will come and go during the day. Better when I sit down. Dr. put me on e antihistamine did not make a difference. Will sometimes feel shaky also but there is no actual shaking. Tested for low blood sugar and came back normal.
