[|Human|] i am nearly 15, female and have had a small lump under the skin about 1" away from my inner right thigh. I first noticed it about 1-2 weeks ago, but though it a zit or something. its about 1/2 cm across and feels about the same deep. yesterday, i noticed it was turning brown on top and was somewhat painful to touch. What could it be?
[|AI|]  Hello and welcome to Chat Doctor, A lump few centimeters inside the thigh could be due to lymph node since many lymph nodes are present at this site. You need to consult your doctor for clinical assessment and aspiration cytology. In aspiration cytology, cells are aspirated and spread on glass slide. These cells are stained and viewed under the microscope. This investigation will determine the nature and origin of the lesion. Further management will depend on the material aspirated. Thanks and take care Chat Doctor.
