Left side head pressure, tender spot, neck issues

[KG81]

Hello, I am new here but I am a little concerned. I am a healthy 35yr old male however I have been dealing with left side head pressure for the last 5 weeks. I don't get a real bad headache but its mostly just pressure and its pretty much with me 24/7. I have noticed when I lay down or go to the gym with my headphones on it is not as bad but always there, I seem to feel it more when standing but again its always there even when sitting at my desk at work. I will list a few of my symptoms below in a moment but I did want to mention the last 2 years have been rough after going through a tough separation with my fiancée and only seeing my son a couple days a week instead of daily so my stress and anxiety was really bad for a while however I am dealing with that better now so I have a hard time believing this is stress related. I am a very anxious person and do not do well at the doctors, my blood pressure and heart rate go through the roof even just at a check up.

The last few months I have not felt like myself, I have had a bad stomach my whole life but it got worse around November 2015 and I was having chest pains and tightness, long story short I saw my doctor multiple times and was diagnosed with GERD and I also had an EKG and Stress Test Echo on my heart which all came out fine thank god. Now a couple months later I was finally feeling a little better, chest issues and stomach still kind of there but no where near as bad and then randomly get hit with this head pressure one Sunday night after just laying on my couch. I went to the doctor after 2 weeks of the head pressure and he tried 2 weeks of muscle relaxers thinking it was my neck, my neck is super tight especially left side where the head pressure is and he told me to stop going to the chiropractor. I was going to the chiropractor for just a couple months before all this happened because my neck and left shoulder always hurt (I work out in the gym and think part of it is from that, I used to lift very heavy but I don't as much anymore). The funny thing is a week before this head pressure started my chiropractor did his usual neck crack on both sides and I remember it almost hurting, feeling different then normal and sent pain through my head. I honestly wonder if he did something to me and if this is from my neck however almost 6 weeks and still feel the same? Advil doesn't do much, muscle relaxers didn't work. I am doing neck stretches and just bought a hand held massager this past week for my neck and head. My doctor did not think brain tumor at my visit based of my symptoms and said my reflexes were good.  Sorry for the long post but hoping for some help, my doctor is now referring me to a neurologist but I am trying to hard to push it off a little more hoping it gets better, I have enough medical bills and I am trying to tell myself this has to be from my neck or something that will heal eventually. I know brain tumors are pretty rare but of course I am having anxiety over that.

Symptoms:
-left side head pressure 24/7.
-some pressure in left eye and ear but not terrible.
-neck issues, especially left side, recently got a massage and the massage therapist said my upper back and neck were extremely tight. Chiropractor although I haven't been in a few weeks doctors orders said my C-1 or 2 joint cant remember which one was out of place. I have been doing neck stretches and using a tennis ball.
-some lightheadedness and fatigue, nothing crazy and could be stress since I think about this and worry all day.
-just noticed this week I have a tender spot on the bone top left back side of head.
-no weight loss, no fever, appetite ok for the most part, stomach ache some days but no vomiting.

Hopefully some suggestions and feedback will help, I will see neurologist if this doesn't improve but again I am trying to wait just a little longer on that.

I forgot to mention I do get a little bit of facial tingles in the left side of my cheek and especially my chin, it is not constant and comes and goes. This did start a couple months before this and I went to the dentist because I still have 3 of my wisdom teeth. He did say they could come out and my bottom right one was coming in a little crooked and could be causing some pressure. He did I could hold off for a bit and it wasnt an emergency and that could be causing some of my chin numbness and tingles. Also I am constantly popping my ears because they feel a little blocked and my nose feels a little congested but this has been going on for a while and is not something new, maybe allergies
