Other insect species, like bees, yellow jackets, wasps, hornets and fire ants actually inject venom into their prey and can not only cause localized pain and swelling, but severe, acute allergic reactions in ...Read more

I have 2 insect bites, 1 on my back 1 on my forearm, both swollen and itchy, i have had them for over 6 weeks now! Not painful at all?

Insect bites: BrendanC,

6 weeks seems like quite a long time for insect bites to heal, although this is possible if you are scratching them frequently which can delay healing. Mosquito or spider bites can take a while to heal and can often leave a small lump in the tissue with darkening of the skin which resolves over time. If you have increasing size, redness or pain, you should see your doctor. ...Read more

Poss. bee sting/insect bite 1wk ago. Had pain for 2days, itchy 1day, then ok. Woke up yesterday w/ red itchy blotches around sting area. What's wrong?

Poss. bee sting/insect bite 1wk ago. Had pain for 2days, itchy 1day, then ok. Woke up yesterday w/ red itchy blotches around sting area. What's wrong?

Not unusual: This is not that uncommon a reaction from a sting. If it does not have pus in it, the problem will likely resolve in a few days. If the problem is persistent, then one needs to consider whether part of the stinger was left in the sting site. If there is pus (unlikely for bee sting), then an antibiotic may be required.See doctor if problem persists or gets worse. ...Read more
