[|Human|] I developed overnight, what I found to feel like a tender semi-hardened bump on my left inner/upper thigh. It felt tender, like a bruise. IThe feeling woke me up a couple of times in the night (but, never at all in the day before).But, in the morning, I can tell that it was tender and didn t go down. It seemed to get bigger. It was on the night of the 11th/morning of the 12th. Now, it s a few days later and the feeling is still there, just slightly bigger, but mostly, harder. I just don t see how something can just develope overnight....confused. Don t know it it s a cyst, or a lymph node...or dare I say...anything else
[|AI|]  Hi, dear. I have gone through your question. I can understand your concern.  Its mostly non-serious lesion.  You may have either some benign cyst or enlarged lymph node due to infection. You should go for examination and if needed to go for fine needle aspiration cytology.  Then take treatment accordingly.  Don't worry about malignant lesion because malignant mass can not develop overnight. So don't worry. Just be relaxed. 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.
