The week after my youngest child was born i was stung by a yellow jacket at the base of my neck above my clavicle. It stung and itched and was slightly swollen as per usual with a sting. Several weeks later it flared up again, itching and looking like a small welt again for a day or so. Months later it happened again. This has gone on every several months for over four and a half years. Have you every heard of this before. It is not terrible or excruciating or anything, just amazing and weird. We are just really curious about it. Is this normal? and why does it happen?
