I am worried and trying to decide if I need to go to a doctor's office or not.

Last night I had a headache in one spot on the left side of my forehead, above my temples and along my hairline. The spot was probably about quarter-sized, and the pain was moderate but dull. For a short period of time if I touched it I could feel a heartbeat (but not the whole time). I also felt some momentary dull pains above/behind my left ear, and the left side of the back of my head, near the nape of my neck. The pain was worsened by movement. I also thought maybe it hurt more whenever I was thinking hard, but I'm sure that was my imagination.
I told myself it was probably because I am tense (I tend to be very anxious), or because I am in the middle of the Rabavert vaccine series and headaches are a known side effect, and went to sleep.

This morning I woke up and the headache was gone, but now the spot is sensitive to touch, like a bruise. There is no visible bruising or swelling. However, now I have some pain/soreness in the sides of my neck and inside my left ear. I could actually see my neck pulsing with my heartbeat too--that was a little strange, but I thought maybe that could still be caused by my anxiety making my heart rate go up (and I get panic attacks). There is also some pressure on the left side back of my head. I've been feeling a little dizzy too (but not like vertigo or the room spinning. It's a sensation I don't really know how to describe). My arms feel a little tired/sore but otherwise I feel awake.

As for recent medical history...I had my wisdom teeth removed about a month ago and all went well. About two weeks ago, I had a minor infection in my left wisdom tooth socket so I was prescribed a week of amoxicillin; however I missed two doses (on different days) so I finished a day late. More recently than that, about one week ago I got bitten by a bat so I'm doing the a rabies vaccine series (Rabavert) and just had my second shot in the series yesterday (Oct. 2). After the first shot, I got really tired and had a minor headache and some nausea, which I attributed to the vaccine since those are known side effects.
Also I'm pretty certain I have high blood pressure; my last two readings were 139/63 and 138/73

So...given the above, is there any reason I should visit a doctor's office? I've had to go so much lately that I thought it'd be best to ask before going.
