I have severe pain in my left clavicle and left back, but I don't know which department to see.

Recently, I have been using my left arm a lot, and I developed frozen shoulder symptoms. I received physical therapy and about three injections.

I started exercising regularly as advised, and now my arms can lift well and move smoothly.

But, since some time ago, the area between the left shoulder and collarbone,

There is pain inside the left back wing vertebra area.

My collarbone was so painful at first that just pressing on it made me gasp, but now it's okay as long as I don't press on it.

The orthopedic department said there are no abnormalities, but they advised me to get a CT scan of the internal medicine area.

My concern is about choosing a medical department.

I usually hold my phone in my hand while lying on the bed or leaning against it, so I think that's why. Also, I have a habit of sleeping with a high pillow.

So, I am also very 고민중 about which hospital to go to for my health check-up.

I'm curious whether this is orthopedics or internal medicine.

I'm also worried whether it's a serious illness.
