Had a tick bite back in May following a ride in the Malverns. About a week later the bullseye rash appeared and I was suffering cold-like symptoms.
Went straight to doctors after seeing was pretty insistent about being treated. Docter spent 10 mins online and reading various books, then immediately took some blood and put me on 2 weeks of high Dioxycyclin (made me feel very nauseous even when taken with food).
Blood test was negative (but interesting to read comments above about the testing), and I suspect the cold was just coincidental as the better half had one too. Guess I'll keep my eyes open in case any further symptons materialise!
Was pretty impressed with the doctor to be honest – she took it very seriously… once she'd done some reading!
