changes to a birthmark

I have had a raised tan-pink birthmark(?) on the back of my head, since as long as I can remember.  Two weeks ago, I brushed my hand back there and for the first time, the bottom portion of the birthmark felt thicker and raised.  Last night, I felt a slight itch or tingle back there and accidently touched it again.  To my surprise the area was much bigger and instead of thicker feels more rounded. It is also red vs. the rest of the birthmark which at this time is tan-ish in color.  I made an appointment for about 20 days from now with a dermatologist.  How worried should I be about waiting this long to get in and about the bump itself.  It hurts mildly as well.

Hi,

You might be able to get your GP to take a look even quicker. When I was tested, my GP did the initial test and then passed me onto the dermatologist after. Took 3 days after he took the sample to get the results back.

Moles & birthmarks are more susceptible to skin cancer, so you're doing the right thing to get it looked at with there being a change to it, but keep in mind, most of the time it winds up fine, so I wouldn't panic. I'm not a doctor, but it almost sounds like a bug bite or some rash being red and how fast it's changing.
