I think I have Lyme Disease
 

I found three ticks on me after a BBQ in the woods/by the river, and now my arms are covered in bites that are really itchy, so I've booked an appointment with the doctor tomorrow... ugh, I have prom on Wednesday, I don't want bite covered arms! FML.

I would go to the doctors if I was you.

my dog had a tick once

Hi Zee, how long ago was this? If you have any bullseye-shaped rashes from the bites then this is an indication it may have been an infected tick(s), although this is not always the case. Take photos of the bites, just in case you need them later, as Lyme Disease symptoms don't really show immediately, it's generally a few weeks or months later.

Hopefully you'll have a knowledgeable doc who can deal with this properly for you. It may be nothing, if the ticks weren't infected then all you will be having is a reaction to the bites. Enjoy your prom in long sleeves:-)
