<s>[INST] I have a lump about the size of a walnut underneath the skin around my upper inner thigh near the groin area.  I noticed it about 10 weeks ago when it was the size of a large grape but has now since grown in the past week.  The pain when I press on it feels like a bruise so not really painful at all.  Hope it's just a swollen node. [/INST] Hi,From your description, you may be correct in thinking it is a swollen node. As it has been present for 10 weeks, I suggest you see your doctor for assessment. There is a possibility it may need further investigation.Regards,Dr K A Pottinger </s>
