I was recently tested for the tick borne illness Erlichiosis. I
matched symptoms upon arrival at ER and it is prevalent in the area. Tests are not back yet. Doxycycline IV antibiotics made a great difference and felt great the next day. However, the following morning I woke with a crushing headache again. The pain being centered at the forehead with even a raised area on it. Even with taking 800 mg ibuprofen no relief was found. Concerned about something else. I am currently taking doxycycline every 12 hrs as prescribed. I have no cough, no runny nose or any other sign of drainage.
