My husband was stung by a couple small bee's on the the head. Within 1/2 hour his lymphnodes under his axilla and in groin was very swollen and painful, more so in axilla. No fever, no trouble breathing, just itching and painful. No hives anywhere else on body. I am a nurse. I gave him 2 Benadryl, 25mg per pill. This was a couple hrs ago. Swelling still the same in axilla, down in groin, but his pain on the right is on a scale of 7 out 10 when he moves his right arm. Left arm normal. Should I take him to ER or continue to monitor him? No swelling on head either.
