Lymph node

Hi ladies! So I usually sleep on my left side, but I rolled over to my right side and there was pain under my armpit. I checked it out and it looks like a swollen lymph node. I knew they could get enlarged for a world of reasons, but is it normal if pain comes with it? I'm telling my mom about it when she wakes up but it's keeping me awake because I know some diagnosises are worse than others with them 😓 and Google just gives me cancer, which I know isn't the only case it could be. Any knowledge??
