Worth a visit to see an Infectious Disease Dr?.,would know exactly what this rash is...if meds aren't working. Just my opinion....
GOOD LUCK...
Hi, understand your anxiety. If the rash is not worsening and if it is responding to the benedryl, continue the same. If worsening then she may need steroids to help with her symptoms. You can request for longer acting antihistamines from your treating doctor. Local measures like ice packs and antipruritic lotions are helpful. Try these. If they worsen then take her to the ER. Regards.
