Advice please

I was diagnosed with basal cell Skin cancer approx 6 years ago. 10 years ago I was diagnosed with cervical cancer and had a radical hysterectomy.  For the past 3 months I have had a tingling sensation under my skin on my back. I have monitored it for 3 months and have had no other symptoms. This week I discovered a dark pigmentation in the same area. I went to the doctor today and she totally dismissed me and said I didn't meet the criteria to be referred and come back in a few months if it doesn't get better. I would appreciate any advice please I'm so worried
