Do you live a region where tics are predominate? It sounds like you have all the symptoms of lyme disease. You might want to see you GP and get a Lyme Tither and or ELISA western blot for Lyme Disease. The test is sometimes negative even if you have lyme disease, but it's worth a shot. You should also try a course of antibiotics for a few months..the best being from the penicillin family.
