Suggest Medication For Severe Pain And Swelling Of Finger

Hi, yesterday I hit my index finger hard enough it made a loud popping noise and a severe pain shot up my finger. my husband said it didnt look serious so I didnt go to the hospital but later that night it started swelling ,feeling kinda numb,&it is stiff so when I woke up today it was swollen and still has a numb feeling and the stiffness. so could it be broke or fractured? Should I goe to the hospital?
