Hello. I m waiting for my appointment with my GP after being seen at an urgent care. I have a 1.27cm lump on the left side of my neck, about 1.5 up from my collar bone. I ve had the lump for at least 4 months. Back when I first noticed it, it felt like a pea so I didn t think much of it. Then, in the past few weeks it has grown and changed shape a few times. It now is about .5 , hard, and doesn t move. The Urgent Care doctor told me that I need to have a biopsy done on it, and did blood work. I didn t think I had any symptoms related to this until reading some articles. Some of which were weakness ( which I thought was related to my Metroprolol), headaches, hot flashes (which I though were related to the hysterectomy I had last year), and anemia (which my doctor is monitoring because it s unexplained). Can you give me any insight? Should i be concerned?
