Blisters
In some advanced cases, blisters would show up around a tick bite. If you also have a rash, then blisters might occur in the middle of this area. They tend to be small in size, which ranges around 1 to 2 millimeters in diameter. Since the condition often develops slowly in your body, you might not notice these signs until it develops after several weeks. It is important to avoid breaking or scratching open these blisters to prevent viruses or bacteria from penetrating. [6]
