Pain in the back of the head accompanied by tinnitus that appears when you forget

I don't usually do anything too strenuous and I sleep around 1-2 AM.

I have insomnia, although it's not severe.

Even so, I don't think it was too much.

Sometimes, when I'm living a quiet life and forget about it, I hear a beeping sound in my ears.

There are times when the upper part of the back of my head hurts a lot.

If you press or release that area with your hand, it will get better.

Should I go to the hospital? Should I go to the internal medicine department?
