What symptom can tick have after biting?

Ticks are usually painless when biting and sucking blood. However, because of the lower plate of the chela and penetrating into the host at the same time, it can cause local congestion, edema, acute inflammatory reaction and secondary infection. In the process of biting and sucking blood, some ticks secrete neurotoxins in saliva, which can lead to the conduction disorder of host motor fibers, cause ascending muscle paralysis, and cause respiratory failure and death.

After the tick bites, it will send out a kind of anesthesia, burying the head in the skin to suck blood. At the same time, it secretes a kind of substance that can be harmful to the human body, which needs to be taken out in time.
