Hi kbryant and welcome to the forum.
The first thing that comes to mind is allergy, sensitivity or intolerance
to some substance ingested : food,drink,medicine or chemical (and less likely from environmental exposure)
To rule this out you may have her do Dr. Coca's Pulse test - free download
It will indicate with satisfactory degree of accuracy, reactions, sensitivities, intolerance and allegies to anything ingested that your immune system treats as offensive.It takes about a week to complete.
One can also do the fast version of this pulse test:
Just sit down and take a rest for about 5 minutes. Take your pulse for a full minute (not 15 seconds x 4! ). Then put whatever you want to test in your mouth and chew it for 30 seconds. Then take your pulse again. If your pulse is faster by 6 beats than before, you are allergic or have a sensitivity to it.
If you have type “O” blood type, use 4 extra beats as the criteria instead of 6 extra beats.
Another suspicion is Leaky Gut Syndrome or Gut Dysbiosis, as an underlying cause, if you want to look it up.
Let me know if you need any details.
Wishing your daughter well!
are the blisters just full of clear liquid, sometimes maybe getting a littl infected, and do they itch horribly---especially if she messes with them--such as popping them?
I have atopic dermatits and I have had tiny blisters similar to this for most of my life. My almost 9 year old daughter is having alot of problems with what I imagine is the same thing---but mostly on her toes right now. they also end up cracking and bleeding. I had the same problem on my feet around her age---it has kind of moved all over my body.
has your daughter been tested for celiac diease? I have 3 children with celiac disease----all 3 had different symptoms. One of them was nauseated for months and the doc kept running tests---but we did not figure it out until her twin sister had some horrible rashes on her knees, elbows and behind.
If you decide to have her tested for celiac, make sur the right tests are done.
