I was stung twice by a wasp on finger yday,still very red hot and swollen,tried taking sting out not sure if all out,can't see any,can't put under h2o?

Apple cider vinegar: If it's still stinging, drench it in apple cider vinegar wait 24 h it will form a pustule once it bursts you can take the stinger out . Secondly if you press on it and do not feel a sharp pain, it means the stinger is out. The swelling you are experiencing is inflammation and toxins. It will go down soon. If it persists for more than a week, with pus, see you nearest urgent care for drainage

Try these things: Here's some things to try. Take some ibuprofen or naprosyn for an antiinflammatory. Try loratadine or benadryl (diphenhydramine) as antihistamine. Put cold water on a washcloth and do some cool compresses to the finger. If it does not calm down after a day or two see doctor. If the swelling or pain is severe at any point go to doctor or emergency department immediately.
