I shaved down below 3 days ago and had sex with my husband the night after. Yesterday morning I noticed a small red lump on my bikini line. This morning it is bigger and painful and the rest of my groin feels tender to touch, like it's bruised. I'm currently suffering from a very strong cold so I'm hoping this is just a case of swollen glands and an infected hair follicle. But could someone please reply and help? Thank you!
