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
