Started getting a sharp pain in the crease of my right leg today never had it before been going on and off all day. iit is now throbbing while i am laying down. should i go to the er?

Groin pain: May be nerve, meralgia parasthetica or sciatica, which may be worse when lying down (try a pillow under your legs). if not allergic or with ulcers try aleve (naproxen) 1-2 tabs twice a day, warm bath. In the older individual we are concerned about masses both ovarian, or lesions in the spien causing the issues as well as clots so would f/u with ER today for d-dimer/ dopplers possible CT
