Mild upper inner thigh swelling. tenderness in area? any ideas what this might be? im awaiting scans but might be days out in our facility?

The scans will probably reveal the cause of the swelling and tenderness. But while One waits, such symptoms are often from contusions and trauma (sometimes inadvertent) like hitting one's thigh on angle of a table. Sitting too long with crossed leg on hard surface can also cause Stress and Strain in that area. Nerve and Blood vessel issues also have to be evaluated. The Doctor will sort it out.
