I've had a (what i think is a lymph node) swollen in my upper, inner thigh for nearly 2 weeks now. please put my mind at ease.

Enlarged nodes: The nodes in your groin function to protect both your lower abdomen and your leg. Think back a few weeks and try to recall if you had any injuries to either that large part of your body, any breaks in your skin. Most of the time your bod can heal itself. If not, see your local doc and hopefully he can help and if not and your groin continues to swell, there is always the option of a biopsy.
