I just wondered if anyone could tell me if I should be worried. I have multiple swollen nodes in my neck and groin... about 5. In addition to that I am extremely tired and extremely itchy only on my lower half and most usually at night. The itch is driving me crazy... I cannot stop, nothing helps it. It burns so bad. Please help. Also, I am having a lot of flank pain sometimes on both sides sometimes only on one side. This has been going on for months.
