[|Human|] A few days ago, one of my toes started itching, then swelled up and turned red at the tip. Then, 3 days ago, I developed a hives like rash covering pretty much my whole body. Today, I have blisters on the affected toe and also smaller ones in the area around it. Went to the doctor and she had me get a blood test for uric acid (testing for gout, I guess). The uric acid test is in normal range - 6.1. The toe is not painful, but itches like there is no tomorrow. I am a 60-yo male, and active - I do water aerobics and walk 2+ miles. Also have been hiking recently. Any ideas?
