On and off head pain

This isn’t exactly migraines but I honestly just need opinions…

The pain can be felt in my neck and on the top parts of my head (like the left and right sides of the top of my head). The pain can also be felt some days in my forehead.

This started back in late august, I had really weird head pain (I’m assuming pressure) for about 5 days, during those 5 days it got worse with each day. It built up to the point where one day I laid down and had rice bags on my head the entire day. I was taking Ibuprofen and migraine relief pills. Fast forward to 3 days later, i was all of the sudden sick. I had something sinus related and was congestion for a week. During this time I still had this head pain. I ended up getting rid of the sickness but the head pain still stuck around. I went to the doctor and they prescribed me amoxicillin. I took the amoxicillin, nothing helped.

Fast forward to today, probably 5 weeks in, I still have this head pain. It’s not constant 24/7 head pain. It’s on and off and then throughout the day sometimes it feels like I’m getting stabbed in my head for like a second and then it goes away again.

I’ve searched Google and looked up many possibilities of what it could be; nothing matches what I have. I have terrible anxiety unfortunately and I cannot live without knowing what’s wrong with me. I’ve tried to shove it aside and ignore it but it seems like it won’t go away. It’s affecting my everyday life and it makes me feel unmotivated.
