Thanks for all your replies, ladies. Since we're on a holiday weekend, I've got a couple more days until I can try to get in to see a doctor. It's almost time for my annual checkup with the allergist, but since this might have a viral component I will try to see the PCP or dermatologist first. I took some photos yesterday and this morning so I'd have evidence of what's been happening.
I'm starting to think the Vaseline is part of the problem, because I think it's causing the skin around my lips to break out. I used it last night without using any lip balm. The right corner of my mouth was a mess of small pimples/blisters when I woke up this morning, and a few more white spots had appeared on my lower lip. Since then I put the Vaseline away and have used just enough lip balm to keep things from feeling dry and chapped, with nothing at all in the corners of my mouth. Things have improved over the course of the day.
My usual treatment for the chronic hives is 10 mg of Zyrtec each day. My allergist has told me I can double that if things get worse, and that's what I did for most of the summer, and just recently went back to taking one tablet per day. I also was taking 150 mg of Zantac twice a day over the summer since that's helped me in the past when things have flared up. I recently reduced that dose to 150 mg per day (I had stopped taking it completely but started to have some symptoms of acid reflux, which I think may have been a rebound effect from the drug, so I've been taking the lower dose since then). I will double up on the Zyrtec again to see if that helps calm things down overall.
The really frustrating thing is not knowing what the cause of the lip problem is (yet). I want to treat it but I'm reluctant to try anything else for fear of making things worse.
BTW if I can't wear wool anymore then I will have to move farther south. I can no longer get through the winter without my Ugg boots and wool socks to keep my feet warm!! But fwiw I haven't worn anything made from wool in months, so if I do have a problem with lanolin it's not being made worse by my clothes.
