I'm so sorry your child is sick.
I've heard conflicting things about fevers. My son had a 101.3 under the arm temperature last week and the doctor I spoke to said that he wasn't that concerned because fevers are an indication that the body is fighting something off.
Are your DD's other symptoms getting worse? Is she okay otherwise? Take a deep breath and give the Feverall time to work. Easier said than done, I'm sure.
