Suggest Treatment For Groin Pain And Nausea

Hi, I'm a 53 year old female and have had severe right side groin pain for 10 days now, which came on fairly suddenly. I am nauseus with it, exercising and stretching doesn't help, and neither heat or cold helps the pain either. The pain is there whether I move or not, but sometimes gets even worse, so much that I think I'm going to cry. Do you have any idea what I should do for this much pain? Thank you.
