I Am Awaiting Biopsy For Extra Tissue On My Right

I am awaiting biopsy for extra tissue on my right lymph node. I am having a lot of pain with this. And have been for months. I have recently started noticing small flat red dots appearing on my arms legs and 1 under my breast. They have faded from red to brown on arms and legs but when first came was red. I am very worried I would appreciate any advice
