I pulled a big swollen tick off my daughters head 2 weeks ago which I suspect had been there a while. Not sure how long they take to completely fill up but this was pretty ripe.
Any way GP said antibiotics not needed and shes been fine since with no rash/symptoms.
As previously mentioned if doxycycline is prescribed it will discolour teeth growing at that time (unerupted in the bone)
Im not one for being concerned as Ive had hundreds on me over the years. As others have experienced this was because I stalked in tick infested areas. I found base layers were good barriers but they would still latch on even around my wrists.
Just my thoughts but I think lymes disease is more likley in certain areas of the country? eg down south
