Supraclavicular lymph node, cough, lung nodule on CT

[PB96]

Female, 25

For 3 years I've had a cough, sometimes dry and sometimes productive. I have health anxiety, and really struggle with getting doctors do take me seriously. I function in my everyday life, study, works, and have a social life.

I also have shortness of breath, and got diagnosed with asthma by my GP. Inhalators didn't help me, and they finally refered me to a lung specialist. He doubts the asthma diagnosis. Along with cough (worse in the morning) and shortness of breath, I now also have:

- An intense itch on both my legs on/off WITHOUT a rash. To the point we're i scratch skin off.
- Pain on/off in my right upper arm. Not from muscle or ligaments and tendons. It's mostly in the evening, moving or not moving makes no difference. Not tender when palpated.

Lung CT show mild/border bronchiectasis as well as an infiltration of 12 mm in my right lung, lower lobe. In the description of the test, one doctor wrote that malignancy could not be ruled out, but when I got phoned my doctor assured me, it was probably nothing.

I have a follow up appointment with my lung specialist next week, and a controle CT in July. But I just discovered I have a supraclavicular lymph nodes that is palpable. Just above my right clavicle. It is small, maybe 0,5x0,5 cm, movable but quite firm.

I worry because I have a lot going on already. And I'm just really tired all the time.

Is it normal that some people (slim?) can feel supraclavicular lymph nodes? Or is this 25 % risk it's cancer like Google says..
