HI, Thank you for taking my question. Approximately 3-4 years ago I experienced some unusual symptoms and I was wondering if you would be able to tell me your thoughts. My symptoms were as follows: dizzy, light headed, saw white spots, unable to focus, this lasted for approx. 30-45 minutes and occurred in the afternoon. After this occurred I thought I may have been bitten by a spider as I had been gardening outside. I had no signs of marks on my body. What are your thoughts??
