concerned

Hi, I am a 42 year old female with problems with an eczema rash for about a year and a half.  It was diagnosed as eczema and seems a bit better lately.  One of the areas that I have had the rash is my face and neck and upper chest.

I have been treating it homeopathically and so the progress is slow.  I noticed something catching on my collarbone the other day when I had my arms raised up.

I felt around and noticed a lump about the size of a small kidney bean.  It is in my left collarbone area.  It must be a lymph node.  There is nothing else around that it could be.   it is soft to the touch and moves around liberally.  I assumed that it was swollen due to the inflammation in my neck but when I looked it up I got really scared.  I do sometimes lately get sweating and the chills and some night sweats (they have diminished at night because I changed my blankets recently).  I assumed that I was in the early stages of perimenopause as I only have one ovary but now I am so worried that I could have lymphoma.

Does it show like this?   I feel healthy, when I sweat I took my temp. and it is normal, I do not have a fever.  I also have bad eczema that can affect your body temperature regulation.  I also do not feel fatigued and everything else seems normal.  I only experience itching as it relates to my eczema and it is not really that bad.

I am also not sure the lymph node is swollen.  It falls into about a 1 cm size but it is the only one that is that size.  It pops out of my clavicle when I raise my arms.  Like I said I am just worried now.  Please let me know if anyone has any thoughts.  I am also a bit of a hypochondriac so some of the sweating could be related to stress.

thanks,
