I had outdoor jobs for several years, so I’ve gotten more than my share. In general I’ve noticed every tick bite I’ve ever had relatively quickly (within the hour). They’ve never gotten large. It generally feels like an itch that gradually becomes very noticeable, or sometimes like a little pinch, almost a tugging sensation. They hurt only rarely. The key is realizing what it is. If you’re not familiar with the sensation, you might ignore it longer than you should. They tend to be around your armpits and under your boobs. It generally takes about four hours before the bite becomes dangerous.
Pull them out by gripping them as close to your skin as you can, firmly, but not too tightly, and pull straight away from the skin, start gently and then pull harder. It should come out. If you’re concerned about disease, you can save the tick and give it to your doctor.
