Unusual lumps

Monica • My names Monica and currently pregnant with my second baby! ITS A GIRL! 💁🏽Aurora Valentina Baltazar 🎀👶🏽👑🌺🌸🌹🌷
So this past week I noticed these unusual lumps in my armpit area. They are interior and hurt a lot . My doctor just told me they're swollen lymph nodes and it comes with pregnancy... That's it. Have any of you experienced this and if so how can I relieve or get rid of them ? Thanks
