I had a sudden onset of hives/rashes on my chest, arms and back along with my glands swelling below the jawline and on the neck.  I took Benadryl and also topical Benadryl and the hives and rash appear to have subsided. However, my glands remain swollen, I have no fever.  What would cause the swelling of the glands?   Also my gums hurt.
Hello thanks for consulting Chat Doctor.do u have throat infection like tonsillitis?? U gums also hurt so could be gingival inflammation or any of your teeth hurt? It could lead to swollen lymph nodes which r mentioning.if swollen lymph nodes doesn't subside u may need antibiotics and anti-inflammatory medicines.either ways consult a local oral maxillofacial surgeon.u said rashes have cm down with topical Ben Chat Doctor. .hope it helps
