Hoping you can tell me, is knot after a tick bite on humans normal?

Tick granuloma?: You might have a tick-bite granuloma. It usually develops days or months after the bite and can take months to years to resolve. His might be caused by fragments of the tick still in your skin or might just have been a reaction to the tick’s saliva. Itching is not uncommon. Bacteria and parasites can often co-occur with ticks.
