Deer ticks are readily noticable when they bite. They are continuously painful. One attached tick 1/2 mm in size can feel like one was struck hard with a splintered 2x4. In the least case, it feels like a stick with a rusty nail, that's being twisted. The lesion for the disease is unique and always noticable. That's the clue that penicillin should be given to prevent any long term effects.
I hope to God you're not a doctor, bcse everything you just said is WRONG.
People rarely, if ever, feel bites from deer ticks. That's why every expert stresses the importance of tick checks when people have been out in lyme-endemic areas. In many cases, people don't realize they've been bitten until they develop a rash.
The lyme bull's-eye is NOT always noticeable. Often, it's in a location where it goes unnoticed, like the scalp, behind the ear, or other unmentionable places that people fail to study on a regular basis. In the case of deer tick nymph bites, the rash may be too small to be noticed. Further, the rash doesn't always present as a classic bull's-eye. It's often mistaken for a simple spider bite or ringworm in people who mount a weak defense to the bacteria.
Pain is usually not mentioned as a symptom. You're welcome to explore the following links from the CDC and IDSA.
