I Had Cervical Cancer 15 Years Ago. They Did A

I had cervical cancer 15 years ago. They did a radical hysterectomy, but I opted not to do radiation or chemotherapy. I believe I was between stage 2A-2B. I have been experiencing pain in my lower left pelvic area, sometimes in my lower right pelvic area, and most recently in my lower right back. Today I had a couple of episodes where my lower legs got severe sudden cramping. The last time I saw a doctor was 2005. Could this be metastasis?
