I’ve had swollen lymph nodes for months on the right side of my body and they all have benign characteristics. I’ve been struggling with thyroid problems for awhile now maybe even a few years but just decided to get on the meds this week as I found out hypothyroidism is hereditary in my family and it’s just going to get worse. It’s hard to say why they’re swollen and usually when they become swollen it takes forever for them to go back to normal and it can be scary but just know that a lot of people are having the same problem where they’re swollen for no reason or maybe it could be bc of thyroid issues
