Started the day yawning a lot but not particularly tired. By early afternoon had what seemed like a headache developing. Soon afterwards had very strong ache above one eye, hurt even more when eating or smiling. Felt slightly nauseous but not actually about to be sick for the rest of the evening. Also stomach felt a bit unsettled. Head felt a lot better but not back to normal by the next evening. Also had some strange muscle movements under my eye - opposite side to head pain.
Wondered what this might be? Possibly a migraine?
