Hello,
This is
Dr. Klarida Papaqako answering your question.
It is normal to have pain because of wasp sting, because it is a skin damage, who results on injection of a material inside of the body (even if it may be little amount) and the sting may remain inside the skin, in the wound.
If I was your caring doctor, I would recommend to:
--If you know you are allergic, or have allergic symptoms (swelling in your tongue,
rash in the body, breathing problem or other vital), go to the ER as soon as possible.
--Check the place of the sting, to make sure there is no string inside the wound, and remove it it that's the case.
--Wash the place with water and soap, apply ice on it for 20 min every hour according to the pain, and apply antibiotic local cream to prevent getting infected.
--Take
paracetamol for the pain as needed, and/or an antihistamine to help with the itching like
Benadryl or
Loratadine.
--If it's been more than 10 years since your last
tetanus booster, get a booster within the next few days.
Hope the information helps.
Take care.
