Lump above my collarbone: any idea what it could be?

So, I noticed this little lump right above my collarbone, and honestly, it’s driving me a bit crazy... it doesn't actually hurt, and it feels like it moves around under the skin, which is kind of weird, and I'd say it's about 1.5cm across, maybe a little bit? You can see a tiny bump if you look closely, but since it shifts around when I touch it, I can't quite tell if it's hard or soft, though I'd guess it's more on the softer side rather than being rock hard or anything... My temperature is hovering around 98.6 to 98.8 degrees, and I checked it again this morning and it hasn't changed size at all, plus I don't really have any other symptoms, except for the fact that I feel chilly quite often during the day (even without a fever), so I was wondering what this could be, because I started reading stuff online about cancer and leukemia and I had to shut Google down immediately before I totally panicked

edit: oh, and now I've also got this redness popping up on my face, kind of on my nose on both sides, almost like eczema or something, it's been going on for about a week now, where the redness flares up a little and then fades back down

Are you dealing with any actual symptoms, like coughing, sneezing, or a runny nose? Or maybe you took a hit or scraped yourself somewhere?

I had this one instance where a lymph node in the back of my neck swelled up to the size of a walnut. It was super tender to the touch, but I didn't have any signs of an infection—no fever, no coughing, nothing. After a few days, the pain went away and it started shrinking on its own, so I managed to dodge antibiotics and having to get a biopsy. (I won't lie, it was pretty unnerving; having a lymph node swell up for no apparent reason, especially in a weird spot like right against my cervical spine)

If it doesn't start shrinking or if it stays the same after a couple of days, or if you start feeling other symptoms, go see a doctor. And honestly, don't bother Googling it. You search for a simple cough and suddenly it says it could be lung cancer. Google is evil. 😁

Honestly, I’m not feeling any symptoms at all, which is actually why I started getting a little worried... though now that I'm really looking at it, maybe it feels more like it's on the lower part of my neck rather than right above the collarbone, but everything is so close together down there, isn't it... I think I'll just hang tight for a few more days to see how things develop and then I'll head over to see my doctor
