I Have A Lump In My Neck Throat, How To Get Rid Off It

I have been a cancer patient since 2006, with Lymphoma, however have been in remission since late 2008. I have just discovered a new lump in my neck/throat area that has brought on swelling and pain to the area. With that, I don't have insurance to go see an oncologist currently, and with the pain from the lump from simply burping or swallowing, difficulty breathing at times, and difficulty talking (the vibrations send pain extremely horribly). I have a very high tolerance level for pain but at times its unbearable. Furthermore, my husband heard me wheezing while I slept a bit. I have checked my tonsils, nothing out of the ordinary there, no sore throat. Mainly the symptoms are pain in the neck/throat, a lump or two in that area, swelling, difficulty breathing, swallowing, talking. I am on the verge of going to the ER without any other options. I have tried Tylenol for pain, and IB Profen for swelling, ice wet rag, and none of it has worked for me. I'm concerned that when I go to the hospital they will send me home because I don't have a current oncologist for admitting me to do any tests. If I can get any help, advice or anything on what to do, what to try, whether or not to go to the ER, and what to expect, possible causes I would appreciate it. There was no trama or injury at all to that area. Please Help. Sincerely, In Pain
