Thanks for the pictures, it helps me to better evaluate. I saw different types of lesions on these. Indeed, we can see the eczema lesions that are apparent. You can also see the pimples that you mentioned. The majority of these pimples really look like insect bites at first glance. One of them, however, has a small white head popping out (as if there was a small infection locally). This one would be something to watch out for, but it must be the same cause as the others. It doesn't look like a reaction to plants either. If it doesn't sting, I wouldn't tend to apply anything (except maybe calamine just in case)
I would suggest continuing to apply cortisone to the eczema lesions and watch for the pimples to develop. It should normally go away after a few days
Also, it is normal that the Reactin did not work right away. The optimal time of action may be longer than Benadryl. However, if it starts to itch a lot, you may want to consider using Benadryl. Although it's numbing, it's more effective for this type of itching
For the headache, it's hard to say at this point whether or not it's related to her other symptoms. However, the headache could be a side effect of Reactin. This symptom too will need to be monitored
Based on what we have discussed, if any of the symptoms develop unfavorably, a doctor will need to be seen for a more complete evaluation
I hope I have covered all your questions.
