I am a healthy 58 year old hispanic male. Don t smoke or drink alcohol. Work out 5 days a week. 20# overweight from eating great new mexican foods. Woke up dizzy Saturday. It lasted a couple of hours. Sunday it lasted a bit longer after I woke up. Today I was dizzier when i woke up, had to hold on to something when mobile, and it lasted for about 5 hours. Remained light headed a few hours longer. Each day it cleared up late afternoon. Only rx I ve been taking last 3 months is terbinafine for toe fungus. Blood tests didn t return any concerns. Have never taken any rx other than this. What are your initial thoughts about these symptoms?
