help if can please

hi recently been suffering from a weird feeling in the left side on my neck,i thought my lymp nodes were up and I got really scared thought I had lymphoma the usually health anexity stuff anyway I wen to the doctors numerous times had chest x rays and blood tests all normal,5 different doctors said my nodes weren't up,

but now my sternoclavicular joint is like rock hard ball but bigger than normal the doctor seems to think its my muscles from neck working its way down due to anxiety and stress,really don't know what to do I should listen but my mind is talking me out of it 

Hi Charliee it is your muscles in spasm due to anxiety.You have health anxiety which you need to address as all reassurance is unhelpful so instead of wasting your time with endless tests speak to your doctor about treatment for anxiety and please stop googling it is not a diagnostic tool.

Yeah I hope so just worried about it just seems to be on my left side,left neck and upper left peck and like a hard ball on my stern joint just seem so weird I scared it's cancer!!!!

Negative thinking and worst-case scenario  have taken over.

 many many people get swollen lymph nodes, tighten muscles  in the neck, shoulders, etc. from anxiety. When we are anxious we tend to tighten those areas and they become rockhard overtime. That happened to me from anxiety and I had to go to physical therapy because it was painful. You do not have lymphoma because the doctor said it's not your gland,  it's muscle.  You would have numerous other symptoms if you had lymphoma. 

 yes, listen to your doctor because they definitely know the difference between a lymph gland and muscle. 

 And even if it was in a large lymph gland that does not mean lymphoma. Any little virus even a cold can call swollen lymph glands in the neck area. My kids got it all the time when they were sick and I've had it numerous times.
