Wore spanx underwear and they made the crease of my right groin and thigh sore. that evening, i felt a small lump under the skin in the same area. four days later, soreness is gone but lump remains. lump is harder to find when laying down. help!

Spanx & Lumps: Spanx are very constricting and if ill fitted can cut off the blood and lymphatic flow through the inguinal (groin) area. Additionally, any hair follicles that are compressed by the elastic of the Spanx can cause a low grade bacterial infection (folliculitis). There are lymph nodes in that area that will enlarge when that occurs. If the "lump" is still present in 10 days, see a MD for assessment.
