Groin pain is not a symptom of sciatica. The main symptoms of sciatica are pain, discomfort and/or numbness in the lower back, buttock or leg. It generally only affects one side of the body, according to Mayo Clinic.
Severity of pain may vary between numbness and sharp, jolting pains, and can also differ between regions on the same person. Although mild sciatica usually fades, visit a doctor if it persists longer than a week or if symptoms worsen, as stated by Mayo Clinic.
Sciatica is caused when the spine presses down on the sciatic nerve, which is where the name derives and along which symptoms occur, as defined by Mayo Clinic.
