I was stung or bitten by something yesterday on my upper arm and now have a huge red welt, over 4" in diameter on my arm. There is a white center to the ring and it appears to be growing. It was a large circle this morning and is now more oblong and spreading wider. When I was first bitten/stung, I had tingling and numbness down my arm to my hand. That went away after a half hour or so. It's very itchy, and cortisone isn't helping much. Does this seem normal or should I be concerned?

What Causes Welt On Arm After An Insect Bite?
HI, thanks for using healthcare magic If the topical cream is not helping then you may want to try an oral anti histamine as well. This would help to dampen the allergic response that you are experiencing. IF the area is uncomfortable then the use of anti inflammatory pain killers such as ibuprofen or cataflam or naproxen would help as well. I hope this helps
