Was diagnosed with upper respiratory infection and sinusitis now my groin hurts?

Maybe: You have had a lot of coughing or straining. Have an examination with your doctor to check for a possible hernia.

Coughing and hernia: Repeated, sudden increases in abdominal pressure such as coughing an sneezing can cause an inguinal hernia. If you feel a lump in the groin, almost certainly this is a hernia. If it persists it gets worse, see your doctor for a physical exam.
