Don’t be so sure about that 36-48 number. In upstate NY I felt a bite on my leg; checked the spot and found nothing there. But I ended up with the ring around that exact spot all the same...
Are you allergic to mosquito bites? I have an allergy to their anti-coagulant or their local anesthetic. When a mosquito latches on, it starts burning, and afterwards, the swelling is as big as a US quarter coin.
I have similar reactions to ticks. The moment they latch on and start working, it starts a painful burning sensation.
