My 32 yr old fiance was lifting weights today and felt like he pulled his trapezious muscles. Right afterwards he started feeling dizzy, spacy, hazy, unfocused, unsteady on his feet, wobbly, weak and had spatial issues. He had a hard time focusing his thoughts and typing a letter. He takes medication for high blood pressure and tachychardia. He takes Toprol. I had him take 2 aspirin immediately. It's been going on for about 8 hrs. now. He's been home resting. What could this be?
