Is there any assoociation with a single swollen armpit lymph node and perimenopause symptoms, irregular periods, when "all else comes up normal?  I switched to a new family physician because I needed to find someone close to work. I saw her in September and I saw her in November. I had a mammogram in September. Mammogram came up normal. Each time I saw this new physician, I asked about a swollen armpit lymph node under, closer topectoral side. She palpated and said, although swollen, they didn't present as abnormal. As I tried to describe the tenderness, she asked when the last time I shaved. I told her two days ago.I am not very hairy, I  shave once a month, etc. I asked if there could be any connection with sacrioalic joint inflammation on my left side and lymph node, she said emphatically "no". Felt light a strange answer as I have had increasing pain in the joint, and the Orthopedic surgeon confirmed the condition. I asked about

having a biopsy on the lypmph node,  she responded. "If you want to have one, then you can have one" and walked out of the room.

I am looking for a new doctor. In the meantime, I am meeting with my OB/GYn (someone I like), for an opinion and a referral. As I am in the throes of perimenopause, I am wondering if any connections have been made with estrogen levels and lymph nodes.

I am 51. I had my first pregnancy at 43. My daughter is 7.5.

Just poking around for opinions until I can get to the bottom of this, rather, to the side of this.
