That appears to be an adult Western Black-Legged Tick. A cousin of the deer tick here in the east. The western black legged tick is the primary carrier of lyme disease in the west, although I don't think you should be overly concerned in contracting the disease since only about 1% of the tick population is a carrier. Unlike the deer tick here in the east, which is more like 60% of the population. I found the following notation online regarding the western black legged tick:
Humans bitten by these ticks may notice intense inflammation at the site of the bite which may be slow to heal. These sores do not necessarily indicate pathogen transmission by the tick (ie: Lyme disease "bulls eye" rash), but are frequently an artifact of irritation due to tick salivary products injected into the bite site.

Hope this helps.

I had left a message with my doctor earlier in the week about the bite and he finally got back to me asking that I come in to see him.

I'm a little concerned simply because I can't see the area on my scalp to keep an eye out for a bullseye. And when it comes to an "x% chance" of getting something my motto has always been ... when you do get it, it's 100%, so why take the chance. Of course that doesn't keep me from hiking in rattlesnake, poison oak and tick country. LOL

Thanks for your input Suzq.
