Hello. For about 2 years, my supraclavicular lymph nodes and under the jaw have been enlarging from time to time (they move and hurt). At first I had no idea what it was about, ultrasound, X-ray - non-pathological, enlarged lymph nodes. After a long time, I came to the point that they get bigger when a cat bites me. The cat is examined, healthy and when it bites someone else, no one has such symptoms. So I started avoiding the cat, the nodes stopped getting bigger, although the supraclavicular node is slightly enlarged all the time, but as far as I know, sometimes it is so that it is not completely absorbed. Recently I was ill and my knots have grown again. Today, however, I woke up with some kind of "lump", next to the sternum, above the breast. My doctor said it was probably a node where I had never had it in such a place. I did an X-ray, I'm waiting for the result, but I haven't been sick recently, I also have no contact with the cat. Is it normal that sometimes the nodes get bigger for no apparent reason? It still worries me.
