[/INST] Hi, thanks for sharing your health concerns with Chat Doctor!  Well, If I were your treating Doctor for this case of a previously itchy groin lump, I would come up with two or three possibilities as follows:1. A resolving fungal infection or folliculitis2. An infected sebaceous cyst or a dermatofibroma3. A lymph node enlarged due to chronic skin infection in the local release take caution not to get injured/infected there! I suggest you to go for an FNAC test of the lump for confirmation and to relieve your concerns! Hope this answers your question. If you have additional questions or follow-up questions then please do not hesitate in writing to us. I will be happy to answer your questions. Wishing you good health. </s>
