Hi I am 18 years old, I am sexual active with my boyfriend, I was tested for STDs and I was negative. I found a Lump on fold of leg near groin area? I noticed a lump about the size of a dime a few days ago on the fold of my leg and groin area where my panty line would be. Its not raised until i move my leg. Its painful to the touch like a bruise and is also hot to the touch. Its also a little red too. I showed it to my mom and she said it was either a infected hair or swollen lymph node, but she isnt a doctor at all. I was looking into some forums and several women said they had the same thing but did not know what it was. Can this be caused by a yeast infection because I think i might have one. I cannot afford medical treatment right now, which is why I came here. Please respond if you think you might know. Thanks!
