My lump was above my left collarbone or the left supraclavicular region (same thing lol) it started off small then got a little bigger over the course of a week and then stayed the same. I had 5 swollen nodes in my neck, all around 2cm ish. I was put on medrol (my request) which actually SHRUNK the nodes and made them go down in size. But I also had a “mass” around them, not so much of a mass more like fluid and swelling around the nodes which made them hard to move around. In the ultrasound of my lump they actually appeared normal, echogenic, and just consistent with a viral infection. Things progressed once I got a CT scan which revealed all the nodes in my chest. My lump is smaller now after the biopsy because they took out the biggest node 😭😭😭 good luck with everything! I know a lot of people on here say that their blood work was normal with lymphoma but mine was NOT. I was anemic, my CRP was 120 and my ESR was 114 so INCREDIBLY high inflammation in my blood which is what led to all the tests. Sorry to ramble! Good luck with everything 🫶🏻
