I m having head sweats, headache, tingling of extremities, double vision, dizzness and tired.... I do have IBS, CAD, C4-5-6 arthiritus, had Afib twice, have 2 stents )LCX). All this started during Bowling last Wed, and had to set out the last tow games. In about 1 1/2 hours was okay to drive home. No problems at night time, only after eating breadfast or bending over moving items, Ken Newton
As you mention double vision, it may be an alarming symptom. Double vision can be because of some lesion in brain stem or may be involvement of neuromuscular junction disorder. You have atrial fibrillation before and cardiac problem already, so you are having strong risk factors for having a stroke. You need to get MRI brain done to look for any stroke and if that is normal, you might require to undergo Repetitive nerve stimulation test to look for myasthenia graves
