<s>[INST] What are the symptoms for a tick bite?  I started getting chills on Wednesday and every joint ached knees, elbows, fingers, ankles, toes and I had a fever too.  All I wanted to do was sleep, didnt eat much and when I did last night I threw up. I feel a lot of nauseous andalittle bit off balance whe I walk.  I have headaches and throbbing in my head.  I never saw a tick but I was in different areas in the last few weeks that could have been infested.
