I went hiking last Sunday, and when I got home, I immediately noticed a bite on my chest. It itched and burned like crazy. I did not really think anything of it, and just assumed it would go away. Well today it worse. It resembles the classic 'bullseye' rash that is associated with Lyme Disease. I was very achy and tired yesterday too. Since I was just hiking in the woods, I very well may have been bitten by a deer tick. Does having this bullseye rash around the bite always mean you have Lyme disease? I am in between health insurances right now, so I need to be absolutely sure that I need medical attention before going to a doctor as I do not have coverage for anything right now.
