My daughter is having a pretty bad reaction to bug bites. Each are swelled more than usual, but this time she has swollen feet and ankles, a swollen cheek and under the eye, swollen knees a little, a slight fever, tired...... Should I give her Benadryl? Or, she had an allergy issue last May and was prescribed a RX for it and also was prescribed Methylpred 4mg in case it got worse....which it didn t.... so I still have it.
