5. The Bull’s Eye Rash
The bull’s eye rash is a well known symptom of Lyme disease that once again makes it very clear that the condition is not merely a case of a cold or a flu.
This appears like concentric circles that get smaller and smaller with a dot in the middle. The circles each vary in their redness and paleness.
Usually, the small dot is the spot where you were bitten by the tick. So even if you didn’t find the tick, you can find this calling card and thereby be fairly certain that it is a case of Lyme disease.
