I was reading up on Lyme Disease the other day (other infections that can come from a tick bite), and it said that sometimes the bullseye doesn't always show up. Alot of times it can be flu like symptoms, and often over looked. They also say that Lyme Disease can be diagnosed as Lupus which affects the joints and internal organs. They say if you pull one or multiple off you put them in seperate jars with a cotton ball that has alcohol on it. Some cases the doctor can send it off to be tested.
Hope your loved one is feeling better?
