This information is very interesting. I read some articles on this topic and there is a lot that is similar to what we went through.
The problem is that the main goal of treatment is stress reduction, which makes treatment in humans a bit subjective.
Some medications I've seen in the articles I've read are:
Antihistamines = mast cell reduction
Prazosin = Local vasodilator
Antidepressants = decreased stress and pain sensitivity
Anxiolytics = sadative, soothing
Painkillers
All medications already discussed here on the forum.
