Hi Greatday05,
I am not disparaging your mother, but do feel compelled to mention the fact that it does not take 24 hours (of tick attachment) for Lyme disease to be transferred. I am unaware of a specific time limitation with regards to the transmission of the disease (or any other tick-born disease for that matter) but do know that it doesn't take a lengthy attachment to become infected with Lyme disease. I've been ill with Lyme disease for 13 years now and can tell you - first-hand - that this disease is a serious matter.
According to my Lyme literate doctor (he also has Lyme disease) there are 4 major variations of Lyme disease. The first two are by far the most common; they account for something around 98% of the infections and generally result in nasty flu-like symptoms and painful joints (typically one or two major joints). If caught early, these types of Lyme disease can be successfully treated with anti-biotic's. I wouldn't consider it a cure though, as occasional flare-ups appear to be somewhat common.
The other two major variations are far more serious; they immediately attack the central nervous system and are far more difficult to control. As with the more common types, these two variations also cause flu-like symptoms, joint pain in multiple joints (including swelling and distortions), memory loss, cognitive disorders, balance problems, etc...
Severe fatigue is also a problem and many of the infected have numerous other health problems as well (too numerous to go into right now).
A Bull's Eye Rash always indicates infection (Lyme disease) but many of those infected never have the Bull's Eye rash. The most effective - though it is often inaccurate too - method for testing is the Western Blot blood test. Be aware that it is fairly common to have false negatives and false positives with regards to Lyme disease tests; a lot of the diagnosis amounts to circumstances and patient symptoms.
The best course of action is prevention. After that, the best course of action is early treatment. Lyme disease is largely misunderstood - including the medical field - and it is rather common for the patient to be misdiagnosed multiple times (I was told I had bone-marrow cancer).
If you get flu-like symptoms be sure to visit your doctor and insist on a Lyme disease test. Be persistent, as many doctors aren't well acquainted with Lyme disease. If necessary, find a different doctor (one who will treat you for Lyme disease). The earlier you get treatment, the better the chances are that you can stop Lyme disease from ruining your life.
Best of luck to you.
