Several lumps

[BUTTERFLY2714]

I have been dealing with enlarge lymph nodes for 1.5 years.  It started with one enlarge lymph node in the subclavicular area.  I had an ultrasound which came back suspicious and was referred for a CT, the very next morning they called me back to have an MRI as the previous CT showed abnormalities and several nodes in my neck area varying in size between 1 to 1.5 cm.  The specialist that I saw specialize in lymph node surgery (he is a surgeon) related to melanoma since I had a melanoma on my right leg in April 2003.  He wasn't concerned with my lymph nodes and didn't want to do a biopsy.  I went back to see him in September because I have been feeling unwell since June.  Again he was not concerned.  I did a blood test and it only revealed ferritin at 38 so I was sent back for another test a week later and it had gone down to 33 but he didn't do anything about it and neither did I since I don't know what it means.  Since then, I have lost 21 pounds since mid August; I have more palpable lymph nodes.  I have constant cold sores on my lips and inside my nose.  I have intermittent fever but I am not sure if it is caused by the cold sores or if I have the cold sores as a result of the fever.  I had cold sores in the past but maybe one every two years.  I went to a clinic yesterday because I felt unwell again and the doc said that I had sign of an infection in my mouth and that my lymph nodes could be caused by a virus that I haven't been able to fight for 4 months.  He is sending me for blood work again.  

I havent received the results but I just notice a lump on the right side of my sacrum.  I had a pilonidal cyst removed when I was 18 where the whole cyst was removed (8 weeks recovery) and I am now 40 years old but it is not in the mid line of my buttock but more to the side.  Could it be another pilonidal cyst or can it be related to my symptoms described above? Thanks for listening and any insight would be appreciated.

Hi,
The lymph node enlargement could be due to any kind of infection,viral or bacterial.Blood work could throw some light on that.Any cancer will spread through the lymphnodes and cause an inflammation,don't delay, consult an oncologist he can help you in overcoming your problem.
A Pilonidal cyst is seen at the bottom of the tailbone(coccyx).This lump on your back should be related to the other symptoms you have mentioned.
Goodluck.
