Stung by a wasp 3 days ago on my eye brow, swelling on both eyes and forehead. taking benadryl (diphenhydramine) should i see a doctor for steroid shot? or wait it out?

Ok: IF not worsening, I would contine what you are doing.

Wasp Sting: If after 3 days, the swelling has not abated, it sound like you may need a round of a steroid taper or as you indicated, a steroid injection. I would have expected the swelling to be coming down now so I do believe you need to receive a little help from your physician.

Bee sting: If you are still swollen. You should see someone. Make sure you are taking the Benadryl (diphenhydramine) correctly: 25 to 50 mg every four to six hours. The 50 will make you a little sleepy. You could also try ice locally to the area 20 m on the hour. You can also try an h2 blocker like Zantac 150g twice a day. Good luck and feel better!

Allergic reaction: If you have taken the Benadryl (diphenhydramine) for 3 days straight and you still have swelling, you may need a stronger antihistamine or a course of steroids. More importantly, get a Rx for an Epipen since it sounds like you have a significant reaction to wasps. You may also consider allergy desensitization.

Wait a bit: Keep ice on it frequently and add Zantac (ranitidine) 150 mg twice a day for couple days. Although usually for reflux, it also blocks histamine and can help remediate this swelling. Steroids are powerful meds and should be used with care. Be well!
