I started a 5 day dose of 500 mg (UTI) last week right before I flew to Chicago for a weekend vacation. Before my flight I was a NERVOUS wreck! I hadn't flown in a while and couldn't believe the anxiety I was feeling. While there, on my 3rd day of levaquin, I went horse-back riding for about an hour, no biggie. The next day, I tried to go on a walk, and had to lay down right in the middle of the woods because my thighs were so sore and my hands were trembling. I had terrible fear of getting back on the plane sunday night, and wanted to write out a will! I was crying my eyes out. Not normal for me. When I got home, I awoke at 3 am extrememly sick to my stomach. I have now been off for 2 days, and the hot sweats and leg pain made me think I had something very wrong. I'm 37 female, healthy.
