Swollen lyph nodes for a year and three months

Lets just start out by saying i have real dry skin and dandruff, basically all my life. But in july of 2009 i broke out on my face, ears and scalp, it was really dry and pealing, red and kind of a burning sensation. I noticed when i broke out swollen lymph nodes came up behind my ears and on the back of my hair line i'd say. Went to the doctor and she gave me elidel cream for my face, so i took put it on my face and it worked with in a few days my skin started clearing up and the 2 lymph node's on the back of my hairline slowly went down and the node behind my right ear went down a little but never went all the way down. So september of 2009 rolls around and i noticed 2 more lymph nodes on my neck, the right and left side. I went back to the doctor and she didnt do anything about it. Then around the summer of 2010 i noticed a swollen lymph node kind of close my jaw and neck, and i went to the doctor and she said it was about 3cm but didnt say anything about the nodes on my neck and behind my ear. So september of 2010 i went to a new doctor and prescribed steriods along with allergy/sinus medicine and i dont know why he gave me sinus medicine because my sinus's feel fine. I took the steriods and after a week the lymph node on the right side went down just a little bit but still noticble and the node close to my neck/jaw went down some, also the steriod had side affect which gave me a stye in my right eye or eye infection i couldnt tell but it was swollen and my eye had a little bump under my eyelid. I dont know what the steriods was for but i would sure like to know?????? they are called "MethylPREDNISOLONE TABLETS, USP 4 mg. Now i'm noticing the node on my left which was never really to swollen all of a sudden gotten a tiny bit bigger but stil not to noticable..........so a day ago i went to the doctor and got blood work done and my red blood count is off, but i do hace sickel cell trait NOT the disease, i've known that since i was born though. Si basically have 5 swollen nodes not really noticable around my neck..HELP !
