<s>[INST] yes i started with a bump that was small on the back of my head, that grew larger in 3 weeks. it had a redness around. Went to the doctors, and he said it was a reactive lymph node. He said not to worry it will go down. It is still there, and now (not to get dirty ) i shaved my below region, and a bump formed around my groin. same hard feeling that was in my head. i thought it was a ingrown hair so i kept shaving but now it has gotten worse. and is red and swollen. i have no idea what it is! [/INST] Hi, dairy have gone through your question. I can understand your concern. You may have some enlarged inguinal lymph node. It is mostly due to reactive hyperplasia.  Other rare possibilities are tuberculosis, lymphoma or metastatic lesion.  However, for that your symptoms and history needs to be evaluated. You should take a course of antibiotics.  If it doesn't respond to treatment then biopsy diagnosis is advisable. Hope I have answered your question, if you have doubt then I will be happy to answer. Thanks for using Chat Doctor. Wish you a very good health. </s>
