I made the mistake of removing a wasp sting stinger without scraping it out using a knife, and my whole forearm swelled up quite a bit. I had a fever the next day as my arm continued to swell.
Is this normal ? Thanks!
Some swelling is normal but if it swelled severely it can indicate an allergy. In either case the swelling should decrease shortly.
If your arm is continuing to swell it can indicate an infection.
See your doctor if it continues OR worsens.
If it hasn't subsided in 2-3 days see your doctor.
