I had bilateral swollen groin nodes last December. Ultrasound said malignant an non malignant tendincies. So they removed the largest 3.2cm on right side. Came back benign. I had low grade fevers all year and my dr diagnosed with FOU. I have had a little pain in my left thigh when walking so I felt around and found 3 very hard non moveable nodes. Largest maybe 2cm They were never this hard before. Should I let my surgeon know an get them biopsied? What s the chance of one side being malignant after right side was benign? Thanks for your help. Can t afford to pay my 15% coinsurance if I don t have to!
